Weapon skins disappearing

So my art deco lancer GL is showing as unlocked now and it switched automatically to the factory skin. Explain this ■■■■■■■■ please.

Were you on private horde? There is a known glitch causing weapon skins to not display correctly.

Same thing happened to me. I unlocked the art deco gl from a supply drop, so I went to check & it still says it’s locked…
