Bug description

I was looking at my friend's corpse and clicked to additional items, he transferred the items to his inventory which caused the crash. This happened on a server. I have a lot of other mods so idk if others are interfering in other ways, hopefully not but if it is absolutely needed I can test for that later.

Minecraft version

1.20.1

Mod version

1.20.1-1.0.14

Mod loader and version

Forge 47.3.6

Steps to reproduce

1. Have dedicated server
2. Have two players
3. Have one player die with additional items
4. Have the other player look at the additional items screen
5. Have the other player transfer the items to inventory and crash

Expected behavior

No crash

No response

I tried to reproduce it and it works perfectly fine in both server and singleplayer, for different players and the same player. Please check if this happens without any other mods installed.
