Was it a new glitch?

Igrmi found some new tech that lets us clip oob basically everywhere on October 1, 2020. because of it, scanner skip became possible. a lot of timesave came from it but the majority of the timesave in the past few years came from competition and practice. the runners have gotten really good at the game in the past 2 years!

How do you perform the glitch?

Crouch and jump into a corner

No this new glitch is completely different, if you jump into a gold bar while slim you can press 1+2 on the same frame, switch pixls, and move through any solid collision.
