Colonists seem to ALWAYS run over and wear scarves regardless of the temperature, I can understand in the cold they will do this, but I am currently playing a desert map, and they are doing the same thing. Sure I can forbid this, but surely there is something tucked away in the code that is causing this very strong preference of illogical attire.

They also do this with gloves, but looking at the stats I can understand why (they offer heat as well as cold protection) even though it does not really make sense.
