Ahh! I was wrong again! :scream_cat:
If you start pocket code, the current project is null but the project saved in the preferences may exist. So deleting some projects will change the current project to be loaded after clicking continue. If there is a method which checks, if the project saved in the preferences exists, use it instead. If not and there's no easy way, you should skip it, because the loading behavior will change in the near future (load in background).
