If I fork the app loader and add my app to it, can I set it so changes on the official app loader are made in my custom one? I'm new to github and don't yet know how it works. Sorry for going a bit off topic.
At the top of your repo there will be a "fetch upstream" button, use that and it'll update the master branch with the current official state. If you've worked in another branch you then need to merge master into that branch.

Yes, this might be the cause. But it never happend with older versions.
