Got all the way to Tier 2 Terminal to find 3 4 star recipes I needed to buy. I was ecstatic...but Basil had 0 inventory of every item in the list. Now that's lame! I don't know if this is a bug or what, but I wasn't happy.
Anyways, I joined a party at about lvl 11 or 12 and then they all went AFK at lvl 12, so I hit "go solo." and went on myself. I don't know if that had anything to do with it...but VERY unfair.
You are required to complete at least one whole level prior to the Terminal to be able to buy any recipes over 1*.
