Fane discovered what looks like some world corruption. I’ve taken the server off line while I investigate. Hopefully nothing too major, maybe a few hours down time.
Update: Up and running again.
MC2 is a fairly big world and it took about 45 minutes to run, here are some stats it returned,
2,929 region files to scan
1,770,233 chunks … 1 corrupted
6.3 Gb current compressed world size
