It crashes either as soon as it joins the world before being able to see the world render or shortly after the world has rendered. When I see water, it does not render at all and I instead I get an xray vision effect.

I have created this issue on Forgery's(Fabrication) issue tracker
FalsehoodMC/Fabrication#539

Fixed on latest versions

I dont even have forgery and I'm getting the same crash
