Confused as how your ore crusher decides if it works with that ore. i made an ore chunk with Exnihilo for a custom ore and it works fine with your ore crusher (suprisingly) but copper also from exnihilo wont process inside.. iridium from themal expansion wont but mana infused will please help .,

Huh copper wont process and it is definitly ore dictionaryed

Ore Crusher determine whether the ore can crush or not by Ore Dictionary. So check the ore you put into Ore Crusher had been registered in Ore Dictionary.

The ore which Ore Crusher does not support is registered in https://github.com/gkbm2013/tinker-IO/blob/1.10.2-GKB/src/java/tinker_io/registry/OreCrusherBanLiatRegistry.java
Hoping this can help you.

Thanks for report! I will fix the problem!

Sorry, it's seems that Ex Nihilo didn't register the item into Ore Dictionary.
