What's the issue you encountered?

My game crashes every time I enter a modded dimension with Biomes o Plenty installed. It's with any modded dimension, I've tried it with multiple. It's also Biomes O plenty and/or Terrablender because the crash doesn't occur when both mods are removed. GPT says the crash report "indicates an issue during chunk generation or loading, specifically an error where a NullPointerException is thrown. The error message suggests that the problem occurs when attempting to invoke a method on a null object reference (cloned.newUniqueness)."

How can the issue be reproduced?

Having Biomes O Plenty and any other mod that has a custom, modded dimension. Simply stepping into the portal or loading in the other world immediately crashes the game. The crash doesn't occur when BOP is removed
