The Atmo Suit bug from 2019 has been resurrected.

We fixed a bug in yesterday's hotfix which was likely one cause of this bug. It's possible the ongoing pathfinding issues we're investigating are also causing it. If you see this happen on 701625 or later please let us know.

I have been playing for the last couple hours (same game as here). The problem is still happening. I thought it was really funny earlier. As I was camping the door to my base I saw one of my 3 suits checkpoint I built to try to alleviate the frustration here with one suit left in it and only 1 suit had been there for almost half a cycle. 2 dups ran towards the checkpoint racing to get the one and only suit and one got it and the other went right out without one. I feel like this is related to them only checking the checkpoints once during their errand selection navigation and not rechecking it if another dup is already committed to the suit. I would love to see per -dock permissions like we have for mess tables so I could just assign each dup to a dock. Best I can do right now is set permissions on the door in front of the dock but this is still clunky.

@EricKlei The bug is still there on 702808.

Thanks for making that test save @Knurek, it was really helpful in debugging the issue.

I may have seen an instance of this 701625. It seems to be rare as I saw it only once, but yesterday I had an unsuited dupe in a walled-off area where the only way inside is via an exosuit station.

I take it the fix is still pending, right?

It should be resolved in
