Hello and thank you for your work!

Wanted to quickly mention that both Stonecutting and Woodcutting do nothing; tested with only Optifine and levelup2 enabled, as well as with and without levelup2's effects toggled on/off via the hotkey.

Optifine: 1.12.2_HD_U_F5
Forge: 14.24.5.2854
LevelUp2: 1.5.8
