A hypothermic dupe gets out of bed to stand around during break time. He then goes to his normal bed instead of sleeping in the med bed resulting in sneezes giving the other dupes the Dead Tired debuff (Now with more -20% Immunity!!).
He returns to the med bed during the next work time.
He should stay in the med bed at all times other than when eating or using the toilet.
Steps to Reproduce
Send your digger to mine out a bunch of underwater tiles until he gets hypothermia. Don't worry, it doesn't take as long as it used to! :) Build a med bed outside of any rooms (don't know if this bug is related to med bed outside of infirmary but my med bed is by the dupe printer, no doors). Watch the dupe hang with the crew during break time and then use his normal bed that night and keep everyone awake.
