I have uploaded a patch to correct some bugs brought on by the code in the 6.2 patch that caused the game to crash. A few other changes were also made to make the shotguns more useful when aiming down the sights.

The pumpshotgun no longer crashes the game when you press the secondary fire button while it's reloading. Both shotguns no longer have a reduced spread while aiming down the sights. This will help them to act more like shotguns 100% of the time. You will need the 6.0 and the 6.2 pak files in your mod filder for this patch to work.
