wont save hotbar

Hey there!

Are you sure that the "Save Hotbar Activator" key is bound to a button in the Controls menu? You can access this by going to Options > Controls and scrolling down to the "Creative Mode" section. By default this key is set to c, however, in the screenshot I've provided, I have it set to o. If this doesn't fix the problem, please let me know and I'll help you out further.
