Issue
It seems that none of the blocks (mob slaughter factory or some twilight forest items) exists in the map but it still causes the server to crash randomly.

Reproduce this without your added mods please.

It's just the original 1.67 version of E2E pack. The same problem also happens in other packs which have mods mentioned in the crash report.

I'm sorry but I have read another crash report :( the actually cause is out of memory.
Anyway thanks a lot for the help !
