I'm trying to implement a challenge mode for one of my games using BB2. Here's what I did and my issues: 1) I placed lock button and unlock logic piece in "level selector" UI. I mapped the destination, world and scene appropriately. 2) I currently have 3 levels 3) Level 1 starts at start screen and ends at start screen. Working fine. 4) Level 2 starts at scene 1 and ends at scene 3. This level starts at start screen instead of scene 1. 5) Level 3 starts at scene 4 and ends at scene 5. The level starts at scene 3 and I get a blank screen instead of level 4. 6) I have aligned the scenes and made sure the start and end distances are matching. Am I missing anything here???
