This isn’t so much a bug as it is an oversight. I just discovered action camera a week or so ago, despite playing HoT since launch (it’s awesome, I love it by the way), but when you try to enter the fractal portal or change the fractal level settings, the game doesn’t pop your mouse out so you can choose a fractal level. On a somewhat related note, I’ve also noticed that when I exit the game, it doesn’t remember that I had action camera enabled. Dunno if that can be fixed because the mouse pops out for the escape menu anyways, but it would be nice not to have to toggle every time I log in or choose fractal levels.
