Ohhh... so that's where I was going wrong. Lol, I knew it was something stupid, and I just needed another set of eyes. So I just would use dpetal= new ItemSeeds(ModBlocks.darklilac, Blocks.FARMLAND), ItemDpetal(); or would I write a new line for it and have two dpetal = new etc.? (Stupid question probably, but bear with me here...)
As for the ItemModelMesher, I suppose it is a bad habit of mine. I've always used it since I was modding, and it never really failed me, but I should really get around to changing soon.
