@cjosie1 To clarify, is it happening to all of your households in all of the lots when you're actively playing them, and none of the NPCs are running like that?
Also, if you have the whole Mods folder moved to your desktop and delete the mentioned cache file then start the game and create a new save and try playing a different household, will the active household you're playing only run rather than walk when they are just going across a small room or similar situation?
Also, please check the patch notes for the November update. https://www.ea.com/en/games/the-sims/the-sims-4/news/update-11-01-2022
For a distance that is 'long enough', most Sims will run now when given a 'go here' command by you. This is what is says in the patch notes. Is it possible this is what you're seeing in your game?
