The log says I m trying to cast class NoiseBasedChunkGenerator to class ChunkGeneratorExtension, after reading the source code, i guess it because the ohter mod's dimension do not use the TFCChunkGenerator which implements ChunkGeneratorExtension as their ChunkGenerator, so maybe you can add an instanceof check before the force class cast and if not then use default value.

This is fixed in 1.2.5, which was released today. Thanks for the report!
