Huge escape exploit that hasn't been fixed yet

Hey all,
So basically on escape maps such as ‘the mines’, that have two different safe room things, any player who wants to be a ■■■■■ can just ruin the game by going in the other room. The toxin just waits at the doorway and doesn’t kill anyone, rather you are just stuck forever, until someone pchanges room. If this never happens, you are just stuck in that situation forever, unable to progress unless you leave. This is obviously just flawed game design and I’m surprised it hasn’t been fixed already because iy would be super easy to do.
