I have had a few tics and runners caught behind closed doors.
The one that comes to mind is in Spiking the Guns opening the door directly in to the ammo store before going up the spiral walkway.
Probably just a combination of circumstances but maybe setting the bots not to go within the door opening arc will prevent then getting stuck back there unless this is seen as a valid tactic (the runner worked its way through the door and got out but not the tic).
