LiveWire, this point is mute given that the mod is now at beta Version 1.8.9 and is pending full release of this Version any day now. In the latest Version the mods weapons system has been completely revamped and play tested to a great degree.
In your Version I recommend that you set both the Computer player bonus as well as the Computer Playe difficulty to high.
Most of the problems people have had were in that they had not set the AI to play well.
And welcome to the forum.
