The Apply button is now held at gunpoint. This may cause slightly dodgy behaviour, but it is better than how it was before.
Before this update, the apply button just didn't work for some people. I initially denied this because I have no idea how it could come about, but I'm going to chalk it down to Unity being Unity. I really had to fix this, because it really messes things up.
So now, I essentially made my own button script that pretty much ensures that the apply button should work no matter what.
