Anyone forced to purchase again on Mac?

[anglaenan23]

I purchased Amnesia: The Dark Descent in my MacBook's app store quite a few years ago and while I understand there is the possibility of updating to run on Catalina -- does anyone have the issue where when you're in the app store, it tells you that you need to purchase the game???
I'm not sure if it's just because it's not able to run on Catalina, or if it's actually going to force me to purchase it again if/when there is an update to play!

I'd hate it if I'm unable to play the game every again!
