Possibly just left clicking, haven't been able to test fully.

Yeah it's just left clicking, doesn't matter what's in your hand.

1.17 btw, the latest version on curseforge

I'm currently quite busy, so a patch might take a while.

"canHarvestBlock" changed names in 37.0.31 back in august.
it is now "isCorrectToolForDrops"
I could throw a PR your way with it fixed if that would make it easier.

I do not take PRs, don't like people meddling with my code in my repo. But your comment helped fixing the crash. So, thanks.
