Duplicants continuously put on exosuit then take it off, and sometimes escape without wearing one

Just noticed that come duplicants who escape have a status that says "Moving to safety."  As if 500 degree oil is safer!  Perhaps because the exosuit dock is currently engulfed in CO2...?  I'm piping O2 to this area to see if that helps.  Still very peculiar behavior, though.

Problem still exists in Rocket upgrade...  Note that there is plenty of O2 at this checkpoint.
