I had pattern providers with an induction card with rainbow furnaces around it and the tps was tanking. When i checked the pattern provider was filled with Forge Energy idk how bc the furnace should not be able to output energy.

This happened on ATM 10-0.7

i think rainbow furnace can output energy from its tooltip?

as to the tps issue, do you have the spark profiler link?

should has been fixed in 1.1.2
