Specifically when using the Hashima Islands map, the server very often will crash on startup.
It is repeatable even with a vanilla installation, and happens about 50% of start requests.
It always points to 'init.c' with 'unknown module' and usually has the same identifier.
Happens regardless of OS and regardless of version. Seems to be an issue with the Hashima Islands mod itself but the admins don't know the cause so I thought I might raise it here on their behalf.
