This will almost certainly be it, as FAWE starts using the chunk as soon as it's loaded

The methods in BukkitWorld for getting entities ultimately only ever get the loaded entities https://github.com/IntellectualSites/FastAsyncWorldEdit/blob/main/worldedit-bukkit/src/main/java/com/sk89q/worldedit/bukkit/BukkitWorld.java#L142-L165 which is completed before any chunks are loaded by FAWE in ForwardExtentCopy

Why did you close this? Having a system to load chunks for operations that otherwise wouldn't is a reasonable addition imo

You labeled this issue as upstream issue, which implies this is a WorldEdit issue. If you feel this is worth an addition, feel free to reopen and apply the enhancement label.

The upstream label was there cos it's also an upstream issue, not necessarily meaning it can/should only be fixed there

When I copy entities, the absolute coordinates are saved or used.

1. select area and copy with entities //copy -e
2. save clipboard //schem save test resp. //schem save test_sponge sponge
3. open Schematic with NBTExplorer

Test Setup:

Can't reproduce the issue of this ticket anymore in 1.19.4 Paper-513 and FAWE-401, I tried as said, but the amount of entities stays the same after 1 minute even. Could be fixed by Paper

Can you open an extra issue for that? It seems to be a problem regarding schematics and entity coordinates, I also came to the same result that pasting the schematic won't have the entities in the loaded and pasted selection, it is different from this issue.
