I didn't catch a video of it, but after throwing bowser at the third bomb, he hit the side of the star ground and fell down into the void instead of landing on the ground on his back. Bowser then jumped back up from the void as if nothing had happened, and I had to throw him at a 4th bomb to kill him.

Has this ever happened to anyone before?

Did you side flip and grab him? EDIT: Actually reading over your comment again makes me understand when you threw him he fell into the void again?, that's strange

Idk why he didn't die

its never happened to me

yeah it's fairly common, happened to another runner just a few days ago

Ok, thanks for the replies guys!

it's a me, a glitch
