Its not too hard to craft Fans(rotarycraft) but i think fans are most harder for the Server as an harvester and an planter
In case you're not aware, the reason we have MFR support disabled is because of a glitch that can cause Magical Crops seeds planted via the MFR planter to spawn fully grown, and when such a crop broken/harvested guarantees a that 2 seeds will drop instead of 1, at least one of which will trigger the same glitch again, causing the seeds to duplicate themselves exponentially. For example, 1 diamond seed can be turned into 1000+ seeds in less than an hour... this is such a game breaking exploit that until the developer of Magical Crops releases a fix for it, we simply cannot allow MFR compatibility, sorry!
Rotarycraft fans are enabled and work just fine for most magical crops except for essence seeds, cobalt and ardite and wither skull which they don't work for though I believe thaumcraft golems work for all seeds still.
