There is supposed to be an x which I can drop into my action bar but I do not see any x. I assume the tools menu is the same as the inventory menu right? I have been through that menu many times and can not find anything like an x to drop into the action bar.
Did you finish the tutorial–the directions that pop up in the lower right of the screen where you begin? As you go through the tutorial, what you need unlocks. The Delete feature is two pencils forming an X, and should be in the Tools menu, assuming you’ve got that far. If there’s still a problem, press F10 to submit a report to the devs.
