HOW DID YOU DO THIS I BARELY GET A SUB 14

what have i done to deserve this? xD

I have recently encountered a very similar glitch in 2-8, in wich I also somehow managed to remove the cloud abilitiy, tho I do not have it recorded and I unfortunately couldn't replicate. It also changed the color of the floor and only went away once I restarted the game. I'm sorry that I don't have any footage of it, but I hope this will be useful in any way.
