Edit: sorry, I realized just as i posted that it was in the wrong board...
Ava's Accumulator is broken. It does half of it's job kinda.. haha
It stops arrows and knives and bolts etc. appearing on ground (well i've only tried knives, but i'm assuming the others too) but it doesn't keep them (well most of them like it should) in your weapon\ammo slot, it just gets rid of them one per shot like normal but then doesn't show them on the ground...so you lose them a lot quicker than if you didn't have teh accumulator on...the opposite effect as to what is desired haha..
