This isn't enough information to tell what's wrong, to tell if this is because the code in the plugin is wrong, or it's a bug in the engine

I had the same log output while developing an import plugin when there was a mismatch between the return value of _GetSaveExtension and the generated file inside .godot/imported. In my case _GetSaveExtension returned "png" while the generated file had "md5" extension. This also lead to constant re-importing of files with recognized extensions when switching between Godot and other windows.

Both problems went away as soon as I changed return value of _GetSaveExtension to "md5".
