Map change and Anti-Aliasing
 

Hello all! :D

I recently installed Battlefield 2 (and Project Reality) in my new computer and it runs pretty good, except for two things:
1. When I'm playing Vanilla (haven't tried this in PRM), I connect to a server, play the map and when the round is over it loads a new map. After finishing the map loading (the 2nd map), it kicks me saying my BF2 content's been modified. If I reconnect, I can play normally.

2. In some guns the Anti-Aliasing causes a strange effect, some surfaces behave like if they were liquid, in the weapons. The easiest weapon to see this is the MP5, in between the receiver and the chamber.

Thanks! :)
