I know it’s not an easy work around, but converting my base floor to ceiling tiles on stable pillars gives me enough room to get out when I fall through. I’ve got a ladder with a hatch leading out so I don’t have to break any building pieces. I haven’t had a chance to test it in single player extensively but I haven’t fell through on single player yet. At this point trying a purge on official is not happening. The pillar floors have kept me from throwing my controller at the game though.
