So I have finally got around to trying to change modifiers on my bows. However, when I try the adjustments don't stick. Example: I am trying to change Silver Bow Mod to be able to Zoom + Double Shoot + Quick Shot which equals 80000070 (according to OP). I change my mod type in Panda's Trainer to 80000070, save in trainer, save in game, reload in game, but mod reverts back to original. I have also tried modifying it and dropping the weapon then picking it back up. No dice. Any suggestions?
Edit: Sorry forgot to mention. I am using US disk version 1.1
