Making a new modpack and getting the following crash on startup:

crash-2019-02-07_16.23.47-client.txt

Clearly a conflict with some other mod. But I can't tell which from the crash report. If you need me to I'll pull the mods out 1 by 1 and see which one it is, but would rather not waste those hours if I don't have to.

Logs attached also:
latest.log
debug.log

The same problem

@Zygus42 I would at least suggest updating the quark version. It seems to be something in regards to adding the hopper recipes, if you need extra help with debugging give me a ping on discord.

@brykkiller this is not a quark issue.

With Quark 1.5:

Hmm, your hopper comment prompted me to remove the mod Diet Hoppers and it works now. So that's the conflict. Did you want me to report it to the author of that mod also ?
