We have run into two issues with MFFS. The first being that if you right click on a Coercion Deriver with a Redstone energy conduit it will crash the server. The second being that the conversion rate for RF to forton is so low is impossible to run any MFFS machines. Doing some digging apparently both of these issues have been fixed if UE, Calclavia Core, and MFFS. Are updated to their latest versions. We have a crash report from the energy conduit crash if its needed just let me know. But seeing as Calclavia acknowledged the issue and had updated to resolve it per his github I figured It wouldn't be necessary.
