There were some issues with the FO1 sounds and ammo mod found in version 1.0 of the expansion and these files might still be sitting around causing trouble. *Note* If you are experiencing odd crashes while in combat, or odd crashes in general I highly suggest uninstalling the game (not just the expansion), reinstalling and installing the latest expansion. It's not required though and old saves will work just fine. Starting a new game is not required, but many of the fixes will not take effect unless you enter the area for the first time (New Reno and EPA are such examples) Thus if you haven't made it too far I highly suggest starting a new game. Hopefully most, if not all, of the issues found in 1.0 are fixed. Version 1.1 of the Fallout 2 Restoration Project is now ready.
