Mae is suffocating while waiting for a "Closed" airlock to open. There is breathable air within reach, but she's really desperate for that tiny bit of clean air in a sealed room.
There's a whole pile of dupes trying to get to that same spot. Mae continues waiting for the airlock to open even after running out of breath:
Notice she is inhaling negative Oxygen. When I changed the airlock to "Auto", none of these dupes would do it, they had to wait for someone else to come open the door. Mae survived in spite of being out of air for a while, meanwhile Pam suffocated on the ladder.
Steps to Reproduce
Created a closed-off room with an airlock. Set the airlock to closed. Let the outside of the room fill with contaminated air.
