dupe seeks O2 past exo checkpoint

I just saw a dupe looking for oxygen pass an exo checkpoint and don a suit charged with oxygen. On reaching the oxygen gas past the checkpoint the exosuit bubble vanished and the dupe stood gasping in the exosuit clothes without the bubble helmet visible anywhere until they regained oxygen from the ambient supply (at 60+°C).

Once they had their breath back, the bubble helmet reappeared and the dupe returned past the checkpoint and took off the suit.

Obviously this is buggy, the dupe should have taken oxygen from the suit supply but did not and instead got it from the atmosphere it was aiming at when obliged by routefinding to don the exosuit. It probably should not be looking at oxygen past an exosuit checkpoint in the first place just as it would not look past a closed door it didnt have access to.
