When I activate Fire at Will, the sound of the Phased Biomatter Beams will revert back to the normal phaser sound effects instead of the new Phased Biomatter sound effects. This is happens consistently every time I activate Fire at Will.
I know, I hate it too. It affects the turrets for rapid fire or scatter too I can't remember which. But this is the case with the destabilized tetryon cannons, and several other much older weapons. historically they never fix these bugs.
