//paste with -x (remove entities) does not work #3315
Description
Server Implementation
Paper
Server Version
1.21.8
Describe the bug
I'm pasting a schematic with //paste -ox (//paste -x triggers the same issue) over a region that is the same size as the schematic. When pasting, the paste happens but an error pops in the game. The console shows the following:
[03:42:13 INFO]: Proxymiity issued server command: //paste -ox
[03:42:20 ERROR]: An unexpected error while handling a FastAsyncWorldEdit command
java.lang.IllegalStateException: EntityRemoveEvent may only be triggered synchronously.

The server runs Paper 1.21.8 1.21.8-58-main@9aaaadf (2025-09-03T22:14:30Z) (Implementing API version 1.21.8-R0.1-SNAPSHOT)
To Reproduce
- Select 2 bounds large enough to accomodate some entities
//copy- Place entities between the 2 bounds
- Edit the structure a bit (add/remove blocks)
- Return to the position you were when you copied
//paste -x- Observe as the blocks are pasted while entities stay
Expected behaviour
Entities should be removed when using -x
