Bug with crafted Robots

This bug appears to be specific to Sentrybots, Munchiebots, and Cleanbots (have not tried the Hydrobot). 

Whenever the bots need to go outside, they use the main front door. But they get stuck inside right before leaving. The front door remains open. The robots have to be moved by turning them off, moving them back to their spot in Build/Buy mode, and then completely selling the front door and buying a new one. The door will not close even if they are removed.
