Tinkers Construct is crashing minecraft. I systematically pulled all my mods until the crashing stopped, then readded all but Tinkers and it worked fine. I have the crash report.

Removing Optifine does work however, the true cause is actually the latest release of Extra Utilities 2 1.10.2 Alpha 1.1.0(a) which is causing this issue. If you down grade to 1.0.1 or prior Optifine works just fine with the Tinkers Construct! In fact that new release (Extra Utilities 2) is causing several mod issues, chisels had the same issue not too long ago.

Remove optifine.
