Dreambloom Petal is not categoriezed under "tradeskill" like others such as Dragon Shard of Knowledge.

Tradeskill isn't ours, After doing some investigation there are over 1000 items that would fall under misc/tradeskill
I've added the following to ultimate under "Knowledge"

			[191784] = true, -- Dragon Shard of Knowledge
			[198137] = true, -- Esoteric Dragon Shard of Knowledge
			[200677] = true, -- Dreambloom Petal

as/if you find others please feel free to create a ticket.
