i’ve just about had it!

my last 02 guy died everytime he got to the stair that would take him out of the lab he was in

the first 03 guy i lost with a stair  
yesterday i again lost hours running into crashes relating to going up the stairs or, like with the brazier, doing what worked above ground  
now again. i was tinkering with logs in a brazier … then foolishly entered the basement to look at how i left it yesterday … and, having done nothing, again loose an hour.

and yeah sure its all my fault for not saving at every f\* turn. damn. in true tradition of roguelikes, whenever you get the slightest bit optimistic this game kills you.

/throws mininuke at the guy who thought he had fixed the stair troubles.

I’m having a similar problem.

While riding a motorbike around a bit and killing a couple of Z I found a house with a basement. After finding a grow room down there, it autosaved and when I try to go back upstairs it segfaults, whether I’ve looted the room or not.

I’m running .3 on the tiny core image.

Stacktrace follows, i’ve also got the save directory backed up and a coredump, but that stuff zips to ~3mb so I’ll prob have to email that if anyone wants it.
