+### Fixed
+- Prefab overrides on the scene are reverted on first load of the scene at first launch [`#1372`](https://github.com/anatawa12/AvatarOptimizer/pull/1372)
+- Animating transform with C# named properties are broken by merge bone [`#1373`](https://github.com/anatawa12/AvatarOptimizer/pull/1373)
   - Animator window won't create such animation but some script generates and it works surprisingly
-- Errors with blendShapes with exactly same name in a mesh `#1374`
+- Errors with blendShapes with exactly same name in a mesh [`#1374`](https://github.com/anatawa12/AvatarOptimizer/pull/1374)
   - Such mesh can be generated with Autodesk Maya or 3ds Max
   - Unity API denies generating such mesh with C# so AAO will rename such blendShapes to unique name to support.
   - Unity Animator does animate first blendshale only so second shape would generally removed by remove unused blendShapes.
