- it happens multiple time, only when another player then host is in Savanah (not even i cave). When host is alone, it is ok (tried 50 floors/day). When guest is alone in cave, it also happens.
- not deppend on undeground level (but first occure at 25+)
- there is always ore vein
- reentry from checkpoint is not helping (holes are in cave, only rocks etc. is renewed)
Update:
- Steam PC
- Explosives/tools combination
