Hello

There is the Crash log : https://pastebin.com/381NzxsN

I read your name in the log , so I think its a bug from your side :)

Thx

-I use :
1.12.1-forge1.12.1-14.22.0.2469
Mantle-1.12-1.3.1.21
TConstruct-1.12-2.7.3.30

Fixed c:

Yup, the new version has been out for two hours so I guess that's long enough for me to expect this.

I'll fix it when I can.

Thx
