Crash in maintennance shaft after quicksaving (WINE issue?)

[666ca40e6165eJML]

I just crashed twice in the maintenance shaft area, right after/while quicksaving. Iirc I was running while pressing alt+s.
Picture of where it happened, crashlogs, and modlist attached.
No idea what was causing it, and I could play along after that just fine. I just wonder...
