Hey, so, does anyone know what this means or what I can do about it? My search online turned up some vague stuff about Vector3. But there’s no back trace, and my project is huge. It’s a mostly working game. Any ideas?

When I searched Google for “unity unsupported type vector” and these were the first three results:
It appears this error is related to a broken prefab or possibly an editor issue. Check the suggested solutions in those threads, such as deleting and recreating the prefab, or removing and re-adding the component causing the error.
Also, review your version control history to identify any changes made to your prefabs before the error occurred and determine which ones might be causing the issue.
