MCPE-96247Overworld Portals link to same portal
When I created a portal in the Overworld in a village and travelled to the nether, when I returned I spawned in a new portal on what I assume is the edge of the chunk. Upon destroying this portal I tried again and ended up in the exact same location in a new portal (pics below).
I then created another portal (note around 3 chunks away from the original) - went through, came back and I ended up in the portal above^ (pics for clarity)
This is frustrating above all bugs I've ever seen on MC

As the note says, using third-party tools is not recommended - in fact I think this bug should be resolved as invalid, but let the staff decide.
However if you wish to delete portal data use the following steps - to my memory I had to delete all portal data for it to resolve. This will not delete the portal blocks themselves.
MCC ToolChest:
- Open your world
- On the left, click data -> portals
- On the right, open data -> PortalRecords
- Click the first one that says 7 entries, then press Shift + Down arrow until you reach the end (the last 7 entries "folder")
- Press Delete on your keyboard
- Save
Universal Minecraft Editor (UME):
- Open your world
- On the left, click View Files
- Double-click db or click the > to expand
- Double-click portals
- Repeat steps 4-6 (and possibly also step 3 first) of the MCC ToolChest instructions
Please note that after deleting the Nether, the Nether Fortress data from the previous Nether will still be carried over, i.e. Wither Skeletons, Blazes will spawn in the same location where a Fortress once was. This is also probably not supported by the bug tracker.
If you are experiencing portals not linking up correctly even though you have never used a 3rd-party tool, you are likely not affected by this bug and in fact you are doing it incorrectly - when you go from the Overworld to the Nether, the game will search for another portal within 128 blocks of the pre-calculated spawning position. It is also 128 blocks the other way around, so if you have a portal at 0, 0 Nether, a portal at 450, 300 Overworld will link to it because divided by 8 is around 56, 38 Nether, less than 128 blocks.
Alternatively the game will try to spawn a portal at the nearest valid location, so a portal at 0,0 Overworld can spawn one at 80, 60 Nether if everything from -79, -59 to 79, 59 is blocked (unable to spawn portal "safely"), which is why when you go back you will end up at a new 640, 480 Overworld portal.
A detailed write-up by a mod of this incorrect linking is done in MCPE-39609 and MCPE-96247.
tldr, resolve this "bug" by deleting all portal data, if your portals still arent linking correctly and/or you have never used 3rd party tools you are probably doing it wrongly
This happens in the non beta version in the realms as well. But my bug, I can go over 1000 blocks away in the over world and when I enter the portal it takes me to the portal that was created first in the nether, then when I come back it puts me in a new portal.
Me too Nathan - I tested it out and even if it takes me to "new" nether and I get brought back to the "same" overworld location - it was always many blocks away and never from the same portal I built
[Helper] Umija5859M - you are entirely wrong - this is a NEW BUG - I am VERY aware of how to set up portals correctly, I have been playing for years- this is WRONG this is NOT a previously resolved issue from 2018 - this is a NEW BUG!!!!!! as of Beta 1.16.100.51 - PLEASE UN-RESOLVE THIS TICKET IT IS NOT THE SAME AS MCPE 39609
I will ask for this to be investigated further. However, please avoid "shouting" by use of ALL CAPS etc. We are all just volunteers who are trying to help.
It would be helpful if you could list the exact XYZ coordinates of your portals (at the time the player enters/exits) and how they currently connect in the summary to make it easier for someone to check against the expected behavior.
Thanks for the screenshots. In the example in images 4 and 5, it looks as though it possibly should have generated a new portal around -218~ 351, which would be more than 136 blocks from the existing portal you ended up at.
In your world, are there any large obstructions or dangerous areas around -218 ~ 351, such as a large amount of netherrack, or a lava lake?
Apologies for the "shouting" - I wanted to make it very clear that this is a new bug that wasn't related to the 2018 one - nothing against you personally at all - I just didn't want it to be missed

Original Portal: -2168, 70, 1816 ~~ this leads to -255, 39, 227 in the Nether. When returning through the same portal in the nether, I end up at -2036, 71, 1819 which is 128 blocks away from my original portal
Second Portal: -1740, 126, 2811, I ended up in -210, 81, 444, - instead of the expected -217, ~~ 351 and when I returned through the portal came out at -1688, 71, 3564
Mega Spud - no there isn't anything like that nearby - it should have brought me out directly into the portal I built so I don't know why it thinks it needs to transport me 100+ blocks (almost 1000 in the second portal...) away from the portal I built...
I'm going to assume that only the "Original Portal -2168 70 1816" and the "Second Portal -1740 126 2811" were created by the player, that all other mentioned portals were created by the game, and that there are no other portals in the area.
For "Original Portal":
OW -2168 70 1816 corresponds to N -271 70 227
so the N -255 39 227 portal is well inside the search range.
N -255 39 227 corresponds to OW -2040 39 1816
the generated portal at OW -2036 71 1819 is very close
the search range for that is X -2176 to -1905 | Z 1680 to 1951
the Original Portal is right at the edge of the range and if you happen to have been at X = -254 when you entered the portal instead of -255, the Original Portal would be outside the X search range of -2160 to -1889.
For "Second Portal"
OW -1740 126 2811 corresponds to N -217 126 351 as you noted.
the search range for that is X -352 to 81 | Z 208 to 479
the generated portal at N -210 84 444 is inside the range though somewhat farther away than might be expected. It's hard to say how the game decides where to place the generated portal. Since the Y coordinate was near the top of the nether it probably had to search farther away to find a suitable spot.
N -210 84 444 corresponds to OW -1680 84 3552
the search range for that is X -1808 to -1537 | Z 3424 to 3695
your Second Portal at -1740 126 2811 is outside this search range, so the game created a new portal
If you find something wrong with my calculations please let me know. Otherwise, the behavior seems as expected, though it is possible that there were some changes in the game between versions that cause it to work slightly differently than before.
As before, the best way to manage portals is to build the nether side portal at the exact corresponding (at least X and Z) coordinates and to remove the game-generated portals.
Thank you for responding so thoroughly!!
Your assumptions and calculations I believe are correct
however
The issue I have is, if I create a portal in the overworld in a safe place, travel to the nether through that portal, then return to the overworld through that exact same portal, I should come out of the portal I originally built? But I have been returning through the exact same portal and being relocated many blocks away for seemingly no valid reason? The game has no need to relocate me to a different portal if I am travelling through a portal I have set up myself (with no other portals around - this was pre the second portal I created to test it later)
So whether or not I build an overworld or nether portal first, provided they are the only portals within that “chunk”, I should only ever return through those portals? Not an entirely new one? At least this was the case pre 1.16.100.51 whereby I could expect to go through a portal and return to the exact same portal as I left in? This surely must be a bug- the game has never translocated portals before - usually the discrepancies between the coordinates happens if as you said, there is a big lava lake or the ocean at the “requested” opposing coordinates so the game adjusts for that... but otherwise it would generate in the exact location and you could travel back and forth without creating more portals elsewhere or ending up in totally different locations (ie more than a few blocks of the calculations after allowing for any obstructions of which in this case there aren’t any)
I just can’t believe that this is an intentional design by Mojang as it makes no sense
I assume videos or gifs cannot be posted here? Otherwise I would do a short video to explain the pictures more clearly as it’s very difficult to communicate this issue with just pictures
When traveling from Nether to Overworld you will not necessarily come back to the original portal depending on how far away the one on the Nether side was generated. In your case, the first generated portal is right at the edge of the range needed to return you to the original overworld portal. Your best solution would be to move the portal on the nether side to -271 ~ 227 and this should always link back to your original portal.
