Try to reload save earlier days but more dupes find their way to disappear.
I find that especially when using fire pole cause dupes animation to freeze for a while and return to normal when climbing or doing something again and sometime dupes jump in random tiles when using fire pole
Just trying out a new fire pole this patch. I'm happy with it but still many bugs.
Steps to Reproduce
When loading save files, not looking at them when using fire pole.
