Is it a Heat block or a Hidden Block, cause in the latest config of railcraft that I've checked in the 1.06 pack of Direwolf20 the hidden block is already set to 0 or o, will have to check for a Heat Block if needed... in 1.5.2 with 20 Magmatic Engines I was producing 80MJ/t how many Magmatic Dynamo would be needed to get the same results now, my main problem at the moment is powering the Binnie Bee's stuff that require a huge lot of MJ (Isolator, synthetiser, Innoculator and such...), some machines even need 200MJ/t to run a single time, theses machines do a fantastic work with bees, but now they are a hell lot harder to power since the energy cells won't accept MJ anymore its a challenge to find something reliable that would keep the machines running 24h/24 (chunloaded on a server)
