Hi! I tried today to add BiomesOPlenty to my modpack. Everything works fine in the overworld, but when I enter the nether, the console spams and a few seconds later the game crashes.

The first crash:

The other ones(after I removed some nether biomes and OptiFine)

I think this issue is fixed in the latest version. The crash was caused by a fluid contact causing an invalid block update in the world.java. I tested all the BOP fluids I could in the nether, and saw no issues
