Game is just crashing

One function of Bootstrap crashed the game (I think lol)

Looks like an incompatibility between OptiFine and BetterFoliage.

But if I turn on Minecraft with Optifine and Better Foliage (Without Bootstrap) it works...
But Better Floiage doesn't work when I load any world.

That's because MixinBootstrap is a library mod which is used by BetterFoliage, If you remove MixinBootstrap then BetterFoliage won't work.

You're best option would be to remove BetterFoliage as it's known to breaks other mods (#9)

Okay, thank you, but where can I download working version of Better Foliage??

There is no working version available, the last update was 6 months ago.

So I need to wait...

Okay, Thank You and good day :)
