So I've read through some of the comments here and wanted to give some general answers:
First of all, I am reading some very nice and encouraging posts here. I don't want to indivdually answer every nice comment, but thank you very much! I really appreciate the kind words and they do make a difference and show me that I must somewhat be on the right path. And they also just sweeten my day, thanks.
Now to the credits. I'll make sure to include a more clear message in the next update that thinks will continue. MIST isn't over yet. There is still a lot of content to come.
And whenever you encounter the "x not in list" error, which seemingly many people are, you can just press ignore and everything should work out nicely. Those errors can happen when you skip a part of a quest and I don't find that skip while testing. Although writing this I realized I can write some easy code to make this disappear forever so... It won't happen in future updates.
