Changed:

Thermal Foundation support altered.
Previously, a single config option enabled Thermal Foundation support.
Now: Simple Ore Generation ores will spawn when TF is present, if enabled, but additional steps are required to remove Thermal Foundation ores from spawning.
First, you must go to config/cofh/thermalfoundation and edit common.cfg, and change 'GenerateDefaultFiles' on line 541 to false"
Then, go to config/cofh/world and rename or delete '00_minecraft.json' and '01_thermalfoundation_ores.json'

The automated feature has been removed at the request of one of the authors.
A simpler version may be coming again in the future, but that is per Thermal Foundation's author's discretion.
