I think I just ran into what DeadStack did, it was a miner in the dwarf fort with no dot facing indicator, I shift-looked and it didn't say sleeping or any status other than what's in the tooltip by default. I reloaded the save and the glyph for the miner entity was gone, but was now appearing in the spotted creatures list on the left no matter where I looked. Artur I'll zip up the save, let me know if you'd like me to send it to you.
