Hello,

i have a problem with your mod, i added it to modpack The 1.12.2 Pack but it doesn't work, i contacted modpack support but they couldn't help me and advised me to comment on you, and now i'm here.
I don't even know how to describe the problem, but i will try, when I run modpack it loads 2 out of 7 and creates a crash report and writes that it was caused by flange mod, I will also attach screenshots and crash log.
Screenshot in game:https://prnt.sc/uybar6
Crash log: https://pastebin.com/ZRYb9smc

I hope you will be able to help and advise me.
I apologize for the poor English.

It looks like you're on an old version of the mod. I think your issues will be fixed with a newer version
