Is it just me or is there something really buggy about the keyboard directions, on MacOS at least. Super confusing the isometric perspective. The four main arrow directions work consistently (although it's weird that they're each diagonal on the map). But Fn+arrow seems to behave inconsistently - I have a lot of trouble moving my units where I expect them to go. Just me?
