Issue
I'm not sure if this started earlier as I didn't realize Thaumic Tinkerer was in the top right of the thauminomicon but when I try to unlock any of the starting recipes (except essentia funnel) the complete button changes to complete.... but doesn't update further. Closing and reopening the thauminomicon doesn't fix it nor does restarting the game.

Thaumic Tinkerers research doesn't complete at all. That is a longstanding bug with the mod. There is a fixed being work on but has to be released yet afaik.

Thaumic-Tinkerer/ThaumicTinkerer#937

Thanks for the update.

The related issue's PR has just been merged.

The issue itself is still open.

After a poke, Thaumic-Tinkerer/ThaumicTinkerer#937 has been closed.

Yaaas! Do you know if there's a new version out yet?

There's no new version on curseforge yet, but there is activity on GitHub. All tasks which aren't enhancements or low-priority have been completed. But I don't know if that means there would be a new release any time soon.

I'll keep an eye out and do some more poking if there's no release in the next few days.
