I can't craft Lead from ore chunks, recipe doesn't exist. Even if i manually write ore id (thermal:lead_ore) in config for lead chunks.

I am also experiencing this.

A reload sometimes corrects this bug.
It is sometimes remedied by picking up a silk touched lead ore from the world, and other times is not.
When it is remedied in this fashion the toast about a new recipe being unlocked shows. When bug present, using the recipe command does not fix it.
