I just obtained the m.2187 graveyard from the Halloween supply drop but it says "available to equip at player level 2" and I cannot equip it. Also I completed the past several challenges in zombies but did not get the rewards. Is there any way I can use the gun as well as get the past rewards for the challenges I completed?
