When activating the ritual of sol with a sigil of the blood lamp in a tiny chest the server crashes. Cant provide logs and such unfortunately because I'm not the server's admin. but this should be easily repeatable.

Just to confirm, do you know which mod the tiny chest is from?

A similar crash so im posting here.
Basically everything is the same, just replace tiny chest with gold chest
crash report:
