Quest: My Feisty Little Chocobo - I broke it :(

Quest: My Feisty Little Chocobo
Quest objective: Deliver gysahl greens to Luquelot.

Issue: I turned this quest in for completion while my inventory was apparently full. I gave the quest giver the 'fresh bundle of gysahl greens' that I picked from the nearby garden, but upon completing the dialogue, I received an error message: "Inventory full. Unable to proceed."

Now I am stuck at the above objective. I cannot pick another bundle of gysahl greens from the nearby garden, and I cannot advance this quest. The purchased gysahl greens from the vendor do not work.

I thought I might abandon the quest and re-do it, but unfortunately there is no 'abandon' button for this particular quest. Any help you can provide to me would be great.

Yeah, I'm having the same issue.
