I’ve been seeing this issue, off and on, for about two weeks. At first I thought it was Z-levels related, but I started a new game without Z-levels and its still happening.
What happens is that there are certain tiles in my base that cause the game to silently lockup and freeze. Not all the time, but sometimes, especially if I do advanced inventory operations near them (or sometimes if I drop things on them). The game stops responding to controls and eventually crashes.
It’s somewhat random. There are no debug messages associated with it. It’s not 100% reproducible.
I know this is a terrible bug report. I’m really sorry. I’d welcome suggestions on how to make this a more useful bug report.
