No bug report submitted yet. I think this may just be my own misunderstanding of how its supposed to work. It's a tier 3 trade skill I'm trying to research.
I have all but one tier 1 trade skill researched to rank 1.
I've researched one tier 2 trade skill to rank 1.
Given that I haven't researched all tier 1 trade skills to get the tier 2 skill. I'm curious as to why I'm locked from tier 3 skills.
I don't recall details of this on the in-game tutorials. Is there another help file I can read before I consider this a bug?
