any plans to port to NeoForge 1.21.1+?

Yes, but no promises, since our devs are busy with life right now. As you might expect from a passion project started over 4 years ago, a lot has changed in our personal lives, and we can't dedicate the same amount of attention as when we first started.
I, for example, was in high school when I joined the team, and now I'm attending university - the change is drastic and warrants my full attention, and any free time I have is spent on other stuff.
Sorry about the long rant, I hope you understand.

Sincerely,
Me :)

I'm completely understand, thank you for the reply.
