I am working with a very large Project which have thousands of flies.But when editor crash and restart the engine start progress to discovering the whole project file,which take a very long time.Is that necessary for engine to search all the file again when the editor crash?Becasuse the search progress is running on another thread,but sometime this action block the main thread and it casue a very bad experience.So if the Unreal editor fix this issue,the experience if engine should much better!
