Hello guys, I don't really know if it's a bug or it happens just with me.
When I check the legacy key box, the hotkeys are ajusted to the current hero, and every time I pick a different hero the hotkeys won't "update", it still the same ones of my last hero. I can fix this by unchecking then checking the box again. But It's pretty annoying, mainly when I forget to do it. It doesn't happens always though.

Am I the only one with this issue?
