I'm playing with two or only just one other friend while hosting the server myself. The Server just crashes sometimes while we are doing a raid and after testing the same savefile on singelplayer it doesn't happen.

There where always two crash reports created at once when the server crashed, here is an example:

crash-2025-09-22_19.17.25-server.txt

crash-2025-09-22_19.16.21-server.txt
