Unequiping Oxygen Mask will drop it on floor

Even worse, if you select the dropped mask and manually equip it on a dupe, it still won't let them pass the oxygen mask checkpoint

Adding detail

I think a "bin" or something within the O2 mask checkpoint which releases the O2 in the mask back into the building and recover some of the ore would be a potential way around this. Not sure if the masks on the floor release their o2 back into atmosphere or not but it does go down when they are idle.

As a very low-tech solution to portable oxygen, this is the intended behavior for the building. That said, we're planning on reworking the oxygen mask station. I agree this one does not work all that well.
