I don't know if it's just me having this issue but the auto-smelt upgrade doesn't work I'm playing on 1.20.1

Just want to update people. Smelting doesn't work, however the hole, 3x3 & tunnelling upgrades do, you have to hold down right click for it to activate, nor left click which mines 1 block at a time.

I'm afraid there are some unfixable issues on the 1.20.1 Forge version, the mod will be moving straight to 1.20.6 so this won't be fixed on that version.
Forge in general is quite buggy so it conflicts with many common pieces of the mod, I hope that with forge's general changes it should get better.
Various things like tunneling will be changed to be clearer in the overhaul update/

Me too, and I don't know what is happening

I can confirm the latest version of Forge, the abilities do not work. Tunneling and smelting do not work for me.
Forge 47.1.1 and Minecraft 1.20.1.

yep STILL not working for me

Having an issue where auto smelting upgrade does not work is there a fix for this?

Same here. Also have the silk touch enchantment on my paxel and it doesnt work.
