Hey I noticed you set it as only being able to working on 1.12 has that changed?

It has not, officially, been tested with 1.12.2 - only 1.12 and 1.12.1 - but... the 3.1 series - ie: the current code - should work on 1.12.2

1.12.2 is too recent for me, in my state of trying to get the mods I have some responsibility for, ported to at least 1.12.1 - Base Metals alone has been more than a weeks worth of work, so far

Do you want me to test it anyways and report bugs?

That would be wonderful! We've had people coming to us on GitHub and helping with Base Metals and Modern Metals, so your help would be appreciated!
