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] InventoryCloseEvent Reason API
|
|
|
|
Allows you to determine why an inventory was closed, enabling plugin developers
|
|
to "confirm" things based on if it was player triggered close or not.
