Gates dont work

[Droll]

Ive been having this bug since 0.97 and its where any form of character has the ability to phase through walls.

What makes this interesting and complicated is that they will path around the gate like they should but if there is combat around the gate it is very common for someone to move through.
There are times where they will ignore the gate completely and run through it but this is sometimes fixed by opening and closing the gate, until it happens again that is.
There is also a path finding bug where characters standing at a gateway will get stuck if your town has multiple gates at different points. For some reason, characters begin thinking that other gates are impeding their movement and wont move until you've opened all other gates.

Rebuilding the nav mesh does not do anything to help.
