Is there a setting on the mover that decides that it's breachable?
Isn't there something breachable on that Bridge Construction map?
Breachable doors isn't the problem. The editor can do breachable doors, I used them on City Block. The problem is that the function that limits who can open the door is missing. Normally on Dockside you can only open the door from the inside, but there is no such limiting option in our editor, so it defaults to where it opens from both sides.
I thought I could solve this by simply making the doors one way movers only openable from the inside. However this messed with the decomeshes and the destroyed doors still blocks the path. I'm assuming the deco mesh is supposed to appear on the next mover step and since the door isn't openable from the otuside and thus doesn't have a mover step there it just stays at 0 and blocks the doorway. I don't see an option to control where the decomesh appears. I'll keep messing around with it and seem if I can figure something out but our only option might be to just restore the original 2.5 version.
