I get this bug a lot, given that my colony has 4 leg amputees lying around wasting my other colonists' time. What happens is they get food poisoning, throw up all over the floor and then, because they're not technically in bed anymore, need rescuing, which involves me manually sending another colonist up to tuck them back into bed.
I assume this is a side effect, if not the same as: https://ludeon.com/mantis/view.php?id=1636 (https://ludeon.com/mantis/view.php?id=1636)
Let's wait until that bug is fixed, but I'm also adding a note to Mantis.
