Rejoining should refill your slot if possible

I do not believe HoS slots open up even if you cryo and ghost. That aside, I would agree there definitely needs to be some mechanism to prevent 8 secoff shifts. Perhaps a return to the previous system but with a popup to remind people cryo’ing to ghost if they don’t intend in returning would work better. The system proposed in the original post would also would help.
