So im playing on 1.12.2 and i want that the Mystical Agriculture seeds can be planted with the MFR Planter and harvested with the MFR Harvester so is there any support for this?

Is minefactory reloaded even on 1.12?

Regardless we aren't adding any more mod support in 1.12.

Yeah im playing on 1.12.2 skyboy/MineFactoryReloaded#709
