Is it too late to report on the bug tracker? I found an issue where if you enter the interface of a shotgun turret, SMG turret, dart trap, electric timer relay, motion sensor, or spotlight, the ability to nerdpole or pick up frames is severely crippled. In other words, your camera has to be in a very specific position to pick up or place frames, and sometimes it won't let you do this at all. A simple relog fixes this.
