Your inventory is full, and I expect that is the reason for being unable to complete the turnin.

Thank you. That worked. It's kind of strange that you are required to have an empty spot in your inventory when the reward is only seals, though. And there was no warning or anything given like normal if you try to complete a quest but your inventory is full.
