Would happen to me and a couple of friends. We would switch servers, and when we would get onto the server, none of us would be able to open any doors, doors we had previously opened earlier on another server. The doors wouldnt even show the prompt of being able to open the door. (unsure if this is related, but i'll mention it. This happened 3-4 servers in a row. When we joined a 5th server, all of our characters were erased and we respawned. Could be a related bug or entirely random occurance.)
