Quest Bug: Yoshitune's Disappearence

[yungsossboss]

I recently completed Mount Kurama and afterwards received a quest to report to Yoshitune who isolated herself next to the entrance of Yellow Dragon Spire. I talked to her and clicked "confirm" to receive the quest rewards, but "Could not receive item due to inventory being full" repeatedly pops up and being the rewards are 5 friendship goldfish and a %50 xp boost, I assure you that I am not full on these items, ive checked and even put all the ones that i do own in the storage and the same thing happens, preventing me from moving on in the main quest line. I can't click abandon quest because the option isnt available. I've re-ran Mount Kurama a second time and nothing has changed. Im hoping i don't have to restart a new character and that theres someway to fix this. Please help

These are the items listed that you get when completing Yoshitsune's Disappearance:

Friendship Goldfish
Ootoro Nigiri
EXP Boost +50%
Prayer Crystal

Now, I doubt you have 99 exp boosts, and you probably did put your goldfish away, but I think you might be full on the nigiri, as most people tend to be.

If you want to get rid of the nigiri of which you have 99 of, simply eat them, or discard by going to the inventory. (This is assuming you have 99 Ootoro Nigiri)
if you have somehow have 99 friendship goldfishes, just go level up your partners.
