There appear to be longer load times between 4.16 and 4.17/4.18 when opening a packaged project.
Possible regression from 4.16
Result: The later version has a noticeably longer load time (4.16 take around 0.2 seconds to load where as it will take around 2 seconds to load in later versions)
Expected: The project would have very similar load times with no changes to the project
