Not sure what map it is again. I'll get screenshots when I can, but there's a siege map with a broken gate that is stuck open on the round start.
It's pretty much an automatic win for the attackers, since they don't have to scale the inner walls.
Attackers start outside in grass, across a moat. They put up ladders in the front to scale the first, low, outer wall, with the objective of opening the outer gate (which I believe cannot be opened, I'm not sure if unintentional or by design). They then *should* scale an inner wall to open the inner gate before being able to move on the flag. But the inner gate is always stuck open. Defenders always have a shield wall up in a vain attempt to keep defense for 7 minutes.
I'll get screenies soon. If someone can get them first, that'd be great.
