I started the game in singleplayer mode on release and today I started a new campaign in coop with my brother. I'm not able to pick up any weapons or attachments I already picked up in my other savegame. I don't know whether this problem existed before the patch or came with the patch but please fix this. It's very frustrating when you want to start a new game and can't pick up new weapons. I don't want to use my other savegame with different progress for coop. I didn't test whether this occurs too if you start a new second singleplayer campaign.
