So I noticed while trying to find a fitting weapon set for this, that the knee pads on the pants, do not stay attached to the legs while moving (at least on Dwarf) Dont know the best way to share photos but.
I do want to mention, I did use the Atomic Recalibrator, it seems to only be broken with Dwarf Males (Dark Irons included)
I dunno, it is missing in the dressing room (left leg on my dwarf) but the in game model displays both kneepads, most of the time (sometimes it glitches out)
Very odd tbh maybe it should be reported in the bug forum?
