I was making a new run for the Normal ending category where I was trying a new route after discovering that you don't need to fight a expert version boss to unlock the robot chapter. Actually all you have to do is to clear the dialogues before you enter the area of the boss and then go back to the bunny train. (I won't send my run yet though because I want to optimize it first and not bother the admin with 10 hours long runs to verify)

However when I ended this run with a good 2min30sec WR gap, I started to spam my spacebar for joy and in the video you get to see what happens : the ropes that where suppose to be cutable only after a +1min long fake credit got instantly cut even before it started. I don't know if this is replicable yet but if that's the case then the true ending category just have a new +1min skip.
