Since 1.9, massive entities (+400 for me, depends on your computer/server) cause extreme lag. Killing the entities fix the lags. A moderator locked my old report without looking the video. By entities I don't speak of mobs only, but Boats, Item Frames, Armor stand and that kind of stuff that don't asks the server the pathfinding. I tried to do the exact same thing in 16w14a, that corrects the pathfinding lag, and it does the exact same lag. In 1.8 there was no lag despite the entities.

Since 18w08a, blue wither heads can fly away through blocks on the first tick(s?). When looking at the first screenshots provided, we can think that the two neighbouring wither skulls are close enough to the edge of the 3x3x1 bedrock surface to shoot blue wither heads away from the surface. But in fact, those blue wither heads are just going through blocks. When looking at the next screenshots, you can notice that the wither can shoot projectiles underneath the 3x3x1 surface. This wasn't the case before 18w08a.
Steps to reproduce:
- Build a 3x3x1 bedrock/barrier area
- Put a fence 2 blocks underneath the middle block of the 3x3x1 surface
- Put an obsidian block 1 block higher from the middle block of the 3x3x1 surface (or a normal block but don't forget the water on the wither main head to prevent it from blowing it up)
- Spawn a wither on the fence (horizontally)
- Place blocks around the 3x3x1 surface and hit the wither with projectiles (snowballs)

Do the server has to calculate Boats and Item Frames pathfinding?
Collision is the real cause. I tried to place 400 chickens in a 1x1 spot, and in a 7x7 spot and the difference is clearly here.
Sorry sir, but I couldn't find a way to reproduce the issue. It seems to happen randomly, or I missed something. I just can tell that it happens.
No. I tried to reproduce the glitch on different maps and it gave the same results.
Confirmed for 18w09a, 18w10a, 18w10b, 18w10c, 18w10d.
Confirmed for 18w11a.
Confirmed for 18w14a and 18w14b.
Confirmed for 18w15a.
Confirmed for 18w16a.
I edited the bug report again to edit the version when the bug first appeared. It seems that the glitch appeared even before 18w08a. I have no access to 17w45, 17w46 and 17w47 but I still have access to 17w43. The bug isn't there in 17w43 and it is there in 17w48, so the glitch happened in the snapshots between 17w45 and 17w47, including those. If some people still have access to the snapshots I have listed, please tell me on which snapshot did
MC-126595first appear.Edited the bug report again. I obtained the access to older snapshots, and it's now official that
MC-126595was here since 17w47a. Unfortunately, I have no idea what caused it.
