Ohh my gosh I must've overlooked it then!! Was it one of the ones that triggers when you land on it?
I think(?!?) Honestly, I think it was just a unique issue with what I did personally. I got to that veryyy last jump after it bottlenecks and missed, so the platform somehow got stuck at the end. I think it wouldn't respawn for me bc the game thought I had made it. Again, it's nothing too serious!! But I just wanted to let you know in case you use this platform layout for future projects! ^_^ <3!!
