Bug in optifine

For those who are searching up this issue and finding this. There is a mod that fixes issues with optifine and forge called OptiForge.

That should work until optifine is fixed @JeNaiKe

Holy! Thanks!
And sorry for bothering

optiforge does not work for me, it crashes my game.

Take it up with them, optifine and optiforge is unsupported by us.
