When trying to destroy any block with dank (level 2, red) equipped minecraft crashes.
Forge version 33.0.21, latest dank version 3.9.

Crash log attached crash-2020-08-28_19.51.21-server.txt

Workaround: drop forge version to 33.0.20.

Seems to be linked to .21 forge update changelog

• Added a new implementation of map(), which returns Optional, and resolves the value in the process.

Works on forge 33.0.20

yep, I need to fix that and clean up some code.

Most likely same crash when right clicking empty space (no block highlighted)

Another log crash-2020-08-28_20.03.11-server.txt

Block placing and bag mode works.
