Crash `java.lang.IllegalArgumentException: Cannot drop air`

[kryakovsky]

Minecraft Version: 1.19.4 Forge Version: 45.1.2 Mod Version: 1.10.0 Single Player or Server: Server Describe problem (what you were doing; what happened; what should have happened): I placed item collector, killed a zombie and server started to crash every time i log in.

Log file link: latest.log crash report

And is there any way to fix the server without backups?

[kryakovsky]

Have to say maybe the problem was in mohist core.

Is it reproduce-able with a regular server? (Aka non-mohist)

[Lothrazar]

Cannot replicate with a normal forge server . vanilla and forge entityitems and itemstacks and SynchedEntityData.java do not have this restriction.

I've tried with a forge server and there was no bug. Sorry if i reported a wrong thing.
