@SonarSonic It isn't fixed in FTB Revelation, using FluxNetworks-1.12.2-4.1.1.34 and sonarcore-1.12.2-5.0.19-20 and forge 14.23.5.2855 or 14.23.5.2854

Sorry, but when I read "Fixed" I assume that the default way is working but it isn't. Simply adding a tbh stupied way/bad work arround with punching even a slowly breakable obsidian block to crush it only on bedrock ... I can only run with my head against the wall for this!

The fire recipie is what should work or add smth. like a transmutation machine block for this because disabling this seems to get rid of the dupe bug which can't be real.

I also don't understand why this affects AE2 Formation Plane but tbh, why not simply check if the item in fire/lava was redstone ore and after it got from this deleted/burned, simply spawn fire/lava proof Flux Dust?

I have now, until this get's fixed correctly, find out a similar way for this but yeah, this obsidian method is trash tbh. because why not moving the obsidian then back automaticly?
