This is not a common occurance at all but I’ve only had it happen playing in the apartment my sim lives in now.

she was painting when she randomly got considered unroutable and automatically reset. A bit weird since she wasnt routing anywhere and she hadn’t even finished her painting.

I googled around and found a 2-3 posts about similar issues with bridgeport and getting found to be unroutable doing regular tasks like watching tv. So not enough that it would be a common pattern so to speak. However, I’m always a bit worried about corruption so knowing whether other people have experienced similar things can put my worries to rest.

It's just one data point, but I had a lot of issues with sims living in Sanguine Arms who worked at the theater. However, that may have been related to a mod I use that adds additional entry points to rabbit holes.
