Yes I got the Olemba Seeds working. This was for me one of many quests with gameobjects that didn’t work. With a completely new build it does. So I think that I’ve messed up the previous build with Navicat. I can’t otherwise explain it, but I’ll stick to MySql (with Workbench) as TrinityCore recommends.
I’ve been following DoctorKraft’s advice from that thread I linked and pulling sql data from all my old sniffs. Where the data is not complete I’ve been making new sniffs on retail. It’s slow and incomplete, but slightly better than waiting for TDB to get updated.
