Building the 1.20.2 branch gives a .jar that causes some Mixin errors, and the branch seems very out of date in general compared to 1.20.1 & the master, so I'm assuming there's no real 1.20.2 support.

Obligatory backport request warning, please port your 1.20.1 final version to 1.20.2. I would do it, but you self-implemented a lot of things that I really don't have the time to try to comprehend with my limited Java experience.

yeah i've done a lot of tinkering with existing game code so i'll do this asap
