I activated the rat trap to put some bait in and the rat trap window opened but then closed just as the day faded into night. I scavenged for the night and after the next day and from then onwards I could no longer access my rat trap.
I made a new rat trap and I could use the new one with no problems but all of my survivors can no longer use my old rat trap even after restarting the game multiple times.
A relocate feature would be great or at least the ability to dismantle anything you have constructed since not being able to move furniture or small rat traps around the base does not seem logical.
