This bug doesn't crash the game.

Description of the problem

How to reproduce:

1.plant some BL plants which have 3D models in the ground, such as Weeping Blue, Sundew or Pitcher Plant.
2. you will find some parts of them are incorrectly dark, just like what these pictures show.
I have marked them with red circles.

Pictures:

That's because Optifine disables Forge's improved lighting system. You can temporarily fix it by going into Forge's settings, disable "Client Settings > Forge Light Pipeline Enabled", save, and then enable it again. But that needs to be done everytime you restart the game so it's not really a solution.
