Can you pinpoint which block should trigger the “faded version” to appear? And does that block get to run or not?
You can try to use the “print to console” block at a few critical points to help you track the program flow.
Also, it is not clear why this project takes so long to load. Maybe you can make a copy of it, delete all sprites/code unrelated to the hanger, so that you can start it quickly as you debug.
