Duplication/unused glitch

I just got the enclave plasma stabilized flamer barrel and locked it so that i wouldn’t accidentally scrap it. Got an enclave plasma pistol and put the mod on. I now have both the individual mod and an enclave plasma rifle. I didn’t have a second one as this was the first one i got and was grinding for. I also put a night vision scope on it, but that wasn’t locked so it was “used” and i no longer have that individual mod
