When you swap from the settings view to level design after 1 or 2 seconds the buttons do some kind of animation. Annoyance is that if you select a map it will be deselected by this animation.

To reproduce:

  1. Open settings tab
  2. Open level design tab
  3. Click on a map
  4. Wait 2 seconds
  5. Map is deselected

It's that the level list is reloaded I'd guess, will look into it later :)
