Confirm below that this issue is not covered on the roadmap or "Whats New?"
I don't think it is :D

Can it be reproduced with just Tinkers Construct? If not, list the other mods required to reproduce the issue.
Thermal Series.

Performant really is the issue. It worked fine without performant.

Duplicate of #4283. Remove performant to fix.

Someone else on the team suggested this could be a problem with incorrectly tagged blocks. So reopening to confirm you do not have performant
