In 2.0.0-.06.0-a10 the cactus seeds and sugarcane seeds are not able to be planted on sand with crop sticks. Not sure what is going on as they were working. Breaking them and then trying to replant is what started the issue.

OK...disregard...this seems to have to do with light level.

Add to this that carrot and potato exhibit the same behavior. I'm assuming melons and pumpkins are the same.

Also if you take an agricraft carrot and plant it in the vanilla style it unplants itself after a few moments. Potatoes do this as well except all potatoes do it making potatoes completely broken.

And all crops do it...Harvestcraft as well...they aren't even planted in agricraft sticks.
