Hey @Jeff_Nelon I have a few questions: have you seen any messages like Overwritten <file-path>.liquid in the logs? what flags are you passing into theme dev? Can you see what file is constantly being synced? Can you post at least the last few lines of your verbose log?

I can’t copy what is being shown in the CLI but I was able to take some screenshots.

This is unrelated to this thread, follow Cannot `dev` theme

I’m also getting the same issue it started today randomly, no clue why its happening. Also this is off a clean theme init on the skeleton theme so maybe its an issue with the latest version of the cli?? I think it happened right after upgrading to the latest version. [image]
