The current 1st place run in Any% Glitchless (https://www.speedrun.com/goose/run/yv3rod4z) clips through a fence in the mini-village at 13:26 in the vid. This makes it invalid for that category, correct?

Hey! Thanks for looking out for any possible cheating!

However, this is not a clip. This is simply getting on top of the fence and simply walking over, and that isn't per se a glitch. A similar case could be made for going over the same fence at 12:53, but that's just lifting yourself over a fence too.

Using a prop to gain height to get over a fence, however, is forbidden. I think that still gets used in other categories where you use the prop to also get on top of the bell tower.

The big distinction here is that you're able to walk over the fence, in both directions, with no object or weird sequence of button presses. If it required a clip or a hover to do, it would not be allowed in glitchless. But since it is only using main movement techniques of the game, we don't define it as a glitch.
