Stuck in Mines: door won't open

[bloodyxnights]

I haven't had this problem, but I have seen two different people in the last week having it, with the exact same door. One of them actually beat down the door with a pickaxe, and even once it was down they still couldn't go in, like there was an invisible wall. They also tried restarting the game and re-loading from a previous save and nothing's doing it.
