After the level 4 glitch in Any%, I've seen many players pause the game after going into each pipe. I can't find a guide on how to do so. Do you manually pause, or is it automated?

I submitted a "Highest Tile" run as 512 (5 Minutes, 120 ms). They denied the run because "5120 tile doesn't exist."

Okay, but I put 512 in my description, 512 block is clearly in the image submitted, so why couldn't the mods just change my time to the correct one? Seems a bit dumb.
