I have equipped the Portable Phaser Cannon Special Issue to a BOFF and it seems that it does not fire at all while he has it equipped. It just glows and doesn't shoot. This also causes the BOFF to not use ANY of his powers. He just seems to stand there and die over and over being no help to the ground missions.
I can't see anything on the info on the weapon or the Lobi store that says it can't be used by a BOFF, so would be good to have this bug fixed. Seems kind of useless to have a weapon that doesn't work on a BOFF when there is no info saying they can't use it.
