I just had this happen to me today - I went to the leve counter, saw the version of the guildleve "A Feast Fit for An Admiral" that asks you to make tomato sauce and rewards black pepper was up, so I went to grab it - had to trade in a finished, but not delivered leve to take it. I immediately went to Bango Zango to get the ingredients for the synth and then went to do it.... EXCEPT the leve had transformed into the R20 version of the leve where you make chicken stock and get pie crusts.
Please fix this - and while you're at it - add a couple more cooking leves that reward something other than carrots or apples. Black pepper is in WAY too many recipes for such a rare drop from hard to find/difficult to kill mobs. You should either make it as a reward in more leves or lower the frigging npc prices. I totally understand that you want players to have an incentive to buy from other players instead of the NPC but no one sells garlic or pepper or almost any cooking drop. It sucks.
