Big issue here that I've experienced and explains a few other permanently bugged barn doors I've found.
So I locked both doors of a wooden garage. I've come back to it probably a week or so later. The game doesn't think its locked now, in that I don't get a prompt to unlock it with my lock pick, I get a prompt to lock. But that prompt doesn't work. Opening the door doesn't work either.
Server resets do not fix it. So a car and loot are permanently unaccessible.
I've experienced this on different doors, all double doors but it might be coincidence.
This needs fixing ASAP.
