Keyframed UVs ------------- As most of all the properties, UV island coordinates can be individually keyframed. By examining the **Outliner** and the **Graph editor** you can realize that each island has fixed location coordinates for the current animation.

If those keframes are needed, you must **Insert** a new keframe upon the old one before saving. [1]: https://i.sstatic.net/QOovK.png
