Sorry for such a basic one. I use realtime combat and essentially have no need for a combat menu. I did not set one up. However on a slightly different note there is a notification ("enemy attacks", "player dies") it spawns using my default main menu, i.e. right in the middle of the screen, very annoying. Try as I might I cannot recall where I set up this notification or where to change what GUI box it uses.
Thanks in advance, and again sorry its so basic.
