Just made a quick map. Placed 1 Barr like AI does and ran into it...did not CTD. Placed another Barr at -19m (like i normally do) and ran into it and it did not CTD. What I think I need to do now is wait until my other buddies who I play multi with come online and see what happens when they do the same like I just did. Every time when they crashed into it, it CTD. When I played with them, I never ran into the BARR (hmmm..I wonder why..
I am now wondering if it has something to do with UBI server. Other than these 2 little glitches, GWX 2.1 runs great and now knowing that there are players/trouble shooters like you that are out there helping sort out problems is terrific.
