WotG Windurst Quest reward bug with new adoulin job

[BobbinT]

I just cleared this Windurst mission quest path for Wings of the Goddess called "The Forbidden Path" where in the end I suppose to get reward of potion based on job I'm wearing at that moment.

But apparently since at that time I was in Rune Fencer which is newer job than the old content itself, I turned up getting nothing for quest completion. No potion whatsoever.

I wonder if anyone who ever done this quest on new jobs (RUN or GEO) has same problems?

Edit:

Apparently the game thinks my inventory are full or something because I need to get the finishing CS for this mission again. After I change to one of old jobs (pre-adoulin), it does finally and properly completed this quest.
