While it wasn't really "broken" before, if plugins use NMS (which they really should't be) and mess with entity management themselves, and get it wrong, they could ultimately corrupt our state expectations. I've been unable to reproduce any issues locally, but these changes are the result of me analyzing the code pretty deeply and seeing about how to make it more durable to abnormal usage. Any servers seeing oddities, please run with -Ddebug.entities=true and send me any logs triggered.

Subject: [PATCH] Always process chunk removal in removeEntity
|
|
|
|
Spigot might skip chunk registration changes in removeEntity
|
|
which can keep them in the chunk when they shouldnt be if done
|
|
during entity ticking.
