Hello, I was doing the chocobo companion quest when this problem happened: When I turned in the gysal greens to the npc, my inventory was full, not letting me obtain reward, i got the error message saying my inventory was full, which is normal, and the npc still had the icon over his head. All is well up to that point. Until I make room in my inventory and talk to him again.

He says: "Have you aquired the greens?" but then absolutely nothing...
