Just thought I would make another post on this to get more attention. Seems to be the only weapon spec that is a boss drop that is bugged. I have completed this mission a while and really do not want to start over to get this spec. Would have redone the mission over and over again until I got it if I knew of the bug before hand. Did not have this issue my first play through and now that I have a better 2nd play thru, I cannot complete my wall stash. Hopefully CDPR makes all weapon...
