Has anyone seen this before? I think it is because I tried to play with an extinct race of Humans. I've never seen it before.
This topic has been raised several times through several of the threads concerning the latest update and human play, but you seem to be the first to provide a screenshot.
Meph and Boltgun have said that it has to do with the script "smartpet," which runs to check the status of demons and other intelligent "pet" creatures that should work as members of your fortress, which may not have been flagged as intelligent. It borks some things, like sending art-hating visiting wagon-pullers to visit you for eternity (don't build slabs, windows, statues, etc. Your visiting haulers will just destroy them).
It is supposed to be fixed in the next update.
