Not a bug, but it does get reported literally every month, so I may end up removing it one day. Hidden corridors can be built before the rooms they lead to, there's nothing odd about this! If you wait around long enough, the other side will get dug out--remember that the complex is still expanding, especially in the lower levels............
Hmm we seam to have misunderstood each other I don't care about the fact that the room was dug out, but to the fact that the emergency access
door was placed in the corner of the room. I didn't know was allowed? ( the emergency access was the top right corner of the room)
I do want to note my wording of door since I know a
tunnel can be placed to a future room but that's not my point
(I have 250 hours of play time I have had my fair share of emergency access tunnels to nowhere)
I don't think it's related to the room being dug out at all, but that their is an access next to the corner of the wall
real question Is an emergency access door allowed to be placed in the corner of a room
