I was working on one of my worlds and I think I pressed something. Little colourful bars appear above the scene numbers. I have 44 scenes. All of the bars are red and one scene has a blue bar above it which keeps repeating endlessly when I play the world. None of the other scenes work even though they are randomized. Any ideas as to which setting I accidentally triggered?
Sounds like you pressed S and set a scene to Solo. Simply press S again and all back to normal. You can also press the M key to Mute scenes.
