Yeah, the following has happened to me multiple times when I ask copoilot to fix something. It updates my code to version A, which is still broken. Then I share the error messages asking for a fix, resulting in version B, which is also broken. Then I share the error messages and copilot confidently changes things back to version A, which is still broken.

It will confidently explain version A is broken because it isn't version B, and version B is broken because it isn't version A. There's no "awareness" that this is cycle is happening and it could go on indefinitely.
