Anyone else had this, I've modded a 9mm with a scope (lovely Gun) when I go to sell my spare unmodded 9 mils my 9mm+ jumps straight into the Traders Inventory even thought I didn't select it to sell but only select the ordinary 9 mils I had spare, you know raise some cash. Just me?

Overall I love this game, I was a bit so so at the start but I love it now.

Hmmm, weird.
The only thing that I have noticed that is similar is when I give my modded guns to my companion, the + goes away and become indistinguishable from normal versions until it returns into my inventory.
I haven't tried to sell any modded guns, since mods seem to rare.

i guess a workaround would be to drop your modded (save before hand just incase) and then sell the unmodded ones.

pain in the ass, but might work...

Genius! I sit back in awe, that I didn't think of that
