There are several Threads to that Particular Problem.
I´m not sure if we ever fixed that Problem.
Zip up your entire TerrainControl Folder (where the Configs are, everything All World configs) Upload it somewhere and I´ll take a look at it.
From the Error I guess there is a BiomeConflict somewhere.
After some Digging, I found out, I already had a hunch several times for that Problem:
The problem is probably caused because of these Biomes:
Mesa (Bryce) Rocks
Mesa (Bryce) Forest
I assume that somehow theres a Glitch and MineCraft mistakes them with the Biome because he cant process Spaces inside the name Properly or something:
Mesa (Bryce) (which has a BiomeID of #165)
You will need to either Remove these Biomes that cause the Errors, or you need to rename them.
In that case you will have to rename each mention of these Biomes aswell as the Biome Configs.
If this error were not rather Common, I would have needed to know that you use BiomeBundle to even remotely get to the Conclusion on where the Error could be. Which would be even mor back and forth and would only waste everbodys time.
Next time please Add these kind of Crucial Information when you use 3rd Party Packs, or provide the Neccessary Configs to determine where the Error lies.
