OMG thanks for this thread, i was freaking out!!!
ALL my skins when i logged back into bf4 were changed, i went from having a beautiful digi blue camo ACR to plain forest green..... i think the game struggled to remember what i had unlocked.....so it just gave me 10 packs again with completely different stuff in it!
At least this isnt GTA.....thank god i didnt lose my progress lol
