I was able to gather at 3:51pm Eastern Standard Time. 2013/12/13
Eorzea Time: 10:48 am
Server Time: 8:51pm.

I would like to trouble shoot this more I could do so by abandoning quest but I feel it easier to turn in and not deal with the bug. I would advise checking into this just a little, its a minor bug that seems to have a chance of occuring but after an inspecific amount of time will be gatherable. i still suspect it may be how things are spawned in world for this quest. Any further investigation would require information on how the items spawn and are handled. This is not the first time this has happen to someone I am one of the many who have been effected by this. Google helped me find that it was an issue for several others, all reported that after an uncertain amount of time. the item was then gatherable.
