Duplicants are becoming stuck in transit tubes

I've noticed that duplicants with lower speed (athletics skill) are becoming stuck in transit tubes. They enter the transit station, get launched and then they stop at some point along the way. I've only noticed that because they become highly stressed.

It's important to note that these duplicants are using suits, and are passing through regions with no oxygen, so, after some time, their oxygen ends, but they don't die, just keep stuck there. When their callories get to 0 they die.

I tried teleporting them out of the tube with ALT+Q. It works, but then they just keep stuck in whatever place I teleported them to. The only way to save them is to select them manually and then use the "move to" command.
