Dear @MrTJP,

I think this issue is more right here because it seem to be not the MrTJP-Core. Instead it seem to be the Compat part. (Sorry for the maybe double post but I don't know how to move this)
MrTJP/MrTJPCore#10

I hope you can help me,

I'm not sure what is happening here, but Minecraft loads properly, with no crashing, for me using the most recent downloads of all CoFH mods and all of Project Red. If it makes a difference, I used the files provided by curseforge in both instances.

EDIT: Looking closer at your crash report, neither your CoFH mods nor Project Red are updated to the newest available versions, I'd recommend trying that first...

@MrTJP,

Was already working on this. I checked every mod for API or Thermal Smeltery - Handlers but I didn't find one...

Sorry for stealing your time,

Dear @ate0ate,

This report is a bit older, in the mean time I (until I posted it) I updated all depending mods. No difference. No, the mod-date is not the reason...

I list here the mods I updated in the time who my minecraft stopped working:

Remove mods one by one until you find which one is causing it. (Hint: it's not TE)

@ate0ate,

You are right: It was EndOres 1.2.1 out of some reasons he changed more than in the changelog was written. Anyway: 1.2.1 seem to have more then this single Issue, stick on 1.1.1 until it is fixed.

It was be a bit difficult to send the mod-author the issue because he doesn't use the usual sides like github. I send him a PM with the issue, no answer jet.

@MrTJP,

Thank you very much, this is very kind from your side. Like I said, sorry for my (miss) report.

I was just curious if you made any progress hunting down the culprit? I use many of the same mods myself. Looking at your updated list of mods that you suspect, the ones I do not use are Tinker's IO, Open Peripherals, Endores, Mystcraft, or Reika's Mods. I suspect Endores honestly. Simply because it would most likely add recipes for TE which when called improperly cause that InductiveFurnace Crash. Just guessing though...

Inductive Furnace, not Induction Furnace, as in the furnace added by ProjectRed.

This crash is caused by some mod doing weird things with the vanilla furnace recipe registration. I will fix this on my end, even though its technically not my fault.
