Why cant i save after simply Re-importing my updated mesh

Can’t save G:/Unreal Projects/Moped/Content/Mesh/LightPole.uasset: Graph is linked to private object(s) in an external package.
External Object(s):
FbxStaticMeshImportData_4
SceneThumbnailInfo_1

Try to find the chain of references to that object (may take some time)?

I keep Getting this error.

when i try to save my current project. ive looked up other similar problems but they all refer to a blueprint object. this is a static mesh with simple materials built with only textures. i changed some things with the light map and re-imported and got this. i imported as a totally new mesh. same problem.

HI Stevendowner -

Can you right click the asset and choose Reference Viewer and then post a screenshot of the Reference Viewer here?

Thank You -

Hey thanks for the reply. I just fixed it.
I simply Closed the project.
Went into theunreal engine asset ■■■■■ and removed the .uasset of the object giving trouble. Reopened the project and imported the new mesh. Then everything was perfect.
Thanks again!
