Icons, for Windows seem to be broken, for Android they work fine, but you have to create 5 of them… this should not be this hard for windows…
I tried loading the UE4.ico (Default) file and pasting my image on-top, and then saving it out again (As a different file), and that seemed to work… We’ll see once I do a build, but it didn’t complain about the .ICO file anymore.
