A buddy of mine did not have the rare Renegade Raider skin and suddenly he had the skin in the locker for no reason he did not buy it because he was not in the shop and be season 1 he does not play it i actually saw him with the skin it was also his account how can it be that he got the skin?
It may be from some mistake of EpicGames
Quite simply, he has bought an Acc and merged the accounts so he has the skins.
