I just started playing this game so I'm not sure if anyone could find a use for this, because once you get into the walls you're stuck in there and have to use the teleport to waypoint thing to get out.

Anyway, it seems to happen within the first 5 minutes or so of logging in, or loading into a new area. If I just start sprinting it appears that the models for the buildings load, but the collision does not. I play on with everything maxed, not sure if that affects the load times or if it's just the server lag.
In short:
1. Load new area or login.
2. Quickly sprint into a building
3. ....Be stuck
I haven't made it to the pvp zone yet so I'm still unsure if this has any use or not.
