Yagolta and the miniboss at Raptor's Roost chests not giving items

[Xepher101]

My friend and I killed the mini boss at Raptor's Roost, picked up the chest, opened it up, and got nothing. Figured it was a one time thing and kept on chuggin' on. Then we just killed Yagolta picked up his chest and it also did not give us anything, didn't say it gave us anything in the chat, and doesn't say it even has anything to give when we scroll over it. Is this a bug? Do these mini bosses not drop anything yet?
