I was playing with Create and Farmer's Delight and -Respite installed, and I don't seem to be able to farm the tea bushes with the Mechaincal Harvester. I thought that a Harvester would collect every stage of the crop except the stage 0 one.
Anyways, I would love to see compatibility between these great mods.

EDIT: I am posting this here, though I use the Forge version. (I just didn't find an issues tab there.)
