Hello, longtime Death Road player here. I keep looking at any% runs and they just skip ALL the events. HOW. I mean I assume that’s been patched due to the age of the runs but HOW!? what was the original glitch? I’ve been looking around but can’t find anything about it.

The original glitch let you close the current window by unpausing then pausing very quickly. This lets you skip almost every event in the game. Here's a video that explains how to do it:

CYOA Skip was patched in the ILEUM update. You'd need a backup of the game from the HUMERUS update to do CYOA Skip. AFAIK, you can only do this by getting a physical copy of the console version (and never updating) or by downloading an older version on Steam.
