Hey Skeppartorsk, thanks for the feedback. I see your point with the tutorial. Can you please try to enable the "Skip Tutorial" checkbox? You should be able to select a different boss in the tutorial.
You should be more challenged on the second one ;)

I did try that, swapping boss didn't work. UI wouldn't update at all.
Edit: now I can get to the 2nd boss but any attempt at moving/adding/changing abilities doesn't update the UI. For most things you can just do the "start fight end fight" toggle to make it update. But when trying to setup interrupt the close button on the window doesn't work and that soft locks the game.
