Steps to Reproduce

Additional Info

Curious, this doesn't happen other times when a surgeon leaves the room? How reproducible is this?

[KeeperSt]

Thanks for fixing it. Now it does not happen no longer. Now a surgeon operates, but there is nobody in the bed, and the other surgeon does not do anything.

[TheCycoONE]

I didn't fix anything yet. Not easy to produce then.

When playing around with #1073 I reproduced it. Though I believe for this one to have a leaving surgeon that is gowned, and especially so for these to happen spontaneously would be due to next(self.staff_member_set), ie this one needs a 3rd doctor involved by the looks. Though interrupting and placing the gowned surgeon anywhere else is achievable to get the same error occuring.
