I have all the right ingredients in the alter (rune of fire, rune of water, wheat and 3 oak saplings) then when it come to clicking the mana spreader to power it, it does nothing.
i have plenty of mana and crafted the fire and water runes with no problems

Botania beta version 39 1.7.2

A screenshot and the mod list would be good, please.

Yes this fixed the problem, thankyou
