In general, the problem is this - at first there were 2 colors for weapons, I completed a couple of missions and came to the seller, but there are no external appearances. Then I collected 5 external appearances for weapons, today I go into the game, play a little, I come to the seller, but again there are no external appearances ... As I noticed, they seem to disappear when you pick up the weapon that you have, you just make duplicates.
