Likely caused by the Tool Progression mod overwriting mining levels. I do not know near enough about forge modding (or Java in general) to fix this myself, otherwise I would have. I haven't tested with Tinkers Construct tools yet, but I would be surprised if everything works as intended, even without TP mining levels.

Final checklist

• I know how to properly use check boxes
• [uwu] I have not used any OwO's or UwU's in this issue.
