end_dragon_fight_ticking_area prevents mob spawning in realm
Steps to reproduce
- Create a world.
- Go to the end.
- Spawn 200 mobs, like sheep, or fish in an aquarium.
- Go back to the overworld.
- Explore various undeveloped areas.
Expected result
Mobs spawn.
Observed
Mobs do not spawn.
After we updated to 1.19.71 all Endermen disappeared on the main End island I'm terraforming. Ive gone in caves with zero light no mobs, the nether has no mobs, not even fish are spawning. I double checked that Mob spawning is on and the difficulty is set to hard. The only mobs that are spawning are from spawners. All villagers and animals we had before the update are still here.

Then central end island now has a ticking area around it on realms and servers that keeps it loaded at all times. See REALMS-11290.
Are you using any behavior packs, or is this in a world made from a template (such as a Marketplace world)? Is this occurring on a realm or server, or a local world? (I.e., does REALMS-11290 describe your issue?)
I do not use any behavior pack or a template either. This is occurring in my local world, a single play data. REALMS-11290 does not describe my issue.
Resolving temporarily as Awaiting Response. REALMS-11290 was resolved as fixed in 1.20.71, is this still an issue in the latest version?

Could you attach a copy of the world to this ticket? If the world is too large to attach, you can upload it to a file-sharing site like OneDrive or Dropbox and then share the download link.

Here you go. I opened the copy and mobs are spawning. But they are still not spawning on the realm.
Thanks for the world. I can confirm that this issue is proximately caused by the large number of mobs you have collected in the area around the end fountain in the end dimension, including 224 tropical fish. Bedrock Edition has a global cap of 200 spawnable mobs. When this many mobs are ticked, environmental spawning does not occur.
The underlying cause is that a recent update added an automatic ticking area to the end dimension in BDS and Realms. The ticking area is called "end_dragon_fight_ticking_area" and is 21 x 21 chunks in size, stretching from -160, -160 to +175, +175.
When you load the world on a Realm this ticking area keeps those 224 fish and the other mobs in that area actively loaded, and that prevents mobs spawning anywhere else in the world. The ticking area does not get created when the world is loaded locally, so you cannot reproduce the issue in a local copy. For this reason I am transferring this report to the REALMS project and renaming it to reflect the underlying issue.
Hi
Does this issue still occur after updating to 1.20.32?
