In the variable management menu, in order to edit game variables, you have to click "edit reader variables", but reader variables make me think of the reader customization variables, which are a different type. The first time I saw this, I looked around for "edit game variables" for a few minutes, it would be nice for new people if this was clarified.
Good point! I’ve changed it from “Edit Reader Variables” to simply “Edit Variables”, which should make it clearer.
