Missing credits and progress after purchase is an extremely high priority and it really sucks that this happened in the first place. I can tell you that people are working on it even as we speak.
We do respond to all the issues but not to everyone's posts and we see what you guys posts.
We're also investigating other issues with progress being lost. If you would like to make sure we see an issue, you can DM me, i may not respond but i share everything i get internally.
