How many exotic weapon bounties can you have at once? I already have super good advice. I currently am working on "A request from Ikora part 2", "depleted hand cannon", and "darkness-infused pulse rifle". I received another Vanguard mentor massive but Xander will not let me turn it in. I'm assuming it's because it would give me one of the bounties I am currently working on or have already completed. Any thoughts?
