Just finished the raid in 2 days. Had my 2 keys yesterday (Armory and Irrigation) finished the raid with a friend of mine today ( so we did the whole raid together and should have the same keys) but as we went back in to unlock the chests I opened my inventory and seen my keys for a split second and they disappeared. All but my ventilator key ( from calus fight) check the raid id's, check cerberus_JC inventory. He can even vouch for this..... this upsets me beyond belief..... Never made new char, didn't log to any other char. Just played the raid 2 days in a row then upon beating calus I lost my keys.... Psn: BurnninTrees
