How to get Cobra Staff because inventory was full when I completed quest

[Dechelsea]

I completed Howl From the Heavens last Saturday. I did not receive the Cobra Staff because my inventory was full at the time and I didn't know it. I cannot figure out how to get the Cobra Staff now. The game said to come back and try again later when I had room in my inventory, but that is a standard message and nothing I've tried to recreate the event where I would have gotten the Cobra Staff has succeeded. I waited till the next game day, then the next conquest tally; I've talked with Valda-Galda; I've re-entered Windurst Walls (S) from West Sarutabaruta (S). I've even clicked on the Windurstian Bulwark numerous times. How do I get my Cobra Staff???

Try and see if there's a resume point or a glowy spot you can check.

There should be a restore point near where you got the CS. It's a glowing ??? or blank space on the ground with light aura or whatever, click it.
