So first of all i exit the server i watched some videos then when i came back and joined another public server a different one from the one i first joined my attachments would disappear from my inventory and my gun, it also happens when i don't play the game for a while like when i close my game open it again and join a server the same thing my attachments would disappear, my ammo does not disappear but my gun attachments do its very annoying and i need to keep going back to military bases just for attachments
