I couldnt find anywhere else i could ask this thats why i opened it as an issue

I couldnt find a 1.12 version anywhere or an explanation why there isnt or might not be a 1.12 version for Dynamic Trees BYG so can someone tell me why there isnt a 1.12 version for it?

BYG in 1.12 was made using MCreator and as such its source code is not open for us to see. Mods that are not opensource won't have addons made
