Did you set up the hotkeys? From the manual:
III. SET UP YOUR HOTKEYS - NOTE: This version of EverCraft only utilizes ONE reaction hotkey bar
A. Run the game
B. Decide and plan ahead of time what recipes you'll be crafting. You need to determine
what technique(s) the recipe(s) use.
C. Run EverCraft 4.0
(The first time you run it you will be asked for the path to where your game is
installed. You must enter it correctly if you plan on using Ban Protection or Tell
Notification.)
D. There are instructions built into the GUI, but I'll give them here again.
E. Click on the Hotky Setup tab to find a representation of your hotkey bar in the game.
F. Click on each "hotkey" and then choose the icon that relates to the one you have on your
hotkey bar in the game. *** EverCraft does NOT configure your IN-GAME hotkey bar. It's up
to YOU to make them match each other.***
Alternatively, you can select the technique you're using from the drop down list below
the hotkeys and it will auto-populate the skills.
If you did everything from the start and finish, and then exited the game via
/exit, and rebooted, it should work. It's ran buggy for a lot of people that I know, but rebooting after setup has helped in some instances.
