You need to remove your config/tfc_structures folder to let mod re-create default configs
Main changes:
- Redstone ore replacement
- defaultWorldgenStructures will be sorted by namespace first
- fallbackToTfcStructuresLoot and defaultEmptyChestLootTable option to CommonConfig
- Deepslate replacement instead of blackstone(blackstone exists in TFC Nether)
- Minor fixes
