[1.90] SMP BUG - Cannot get seed bags from certain crops

I have a set of crops for each type of crop now, and I've noticed that I have not received a single crop from certain types. This includes Wheat, Pumpkin, and Melon. I get seed bags almost every other harvest from Reeds, Nether Wart, and Cocoa. I've gone through about 30 generations of a roughly 16-plant wheat/melon farm and haven't gotten a single seed. Don't tell me they are this rare?

But, I did crossbreed two reeds into a wheat plant which DID drop seeds. So I have wheat seed bags now, but not from regular planted wheat plants.

Quote from RichardG

Vanilla crops with growth 1 gain 1 resistance 1 are meant to drop vanilla seeds instead of a seedbag.

My nether wart has 1/1/1 and drops seedbags... Wait, so that means you can only start crossbreeding with plants other than wheat, melon and pumpkin??

So the main thrust of this decision is to encourage people to use reeds to start their crossbreeding? (I noticed you can't plant flowers anymore, and cocoa is sort of a difficult plant to start with).

Ahhhhhh, that makes so much sense. Thanks!
