Reasons why this is the best game ever : 1. Dinosaurs 2. Truck 3. Zoom Zoom

I was going through some of my saved bundles from a long while back, and my key for Dino Zoo Transport Simulator will not activate. I get a message saying 'Duplicate Product Code' or something along those lines. I just tried to redeem my key for this game from the Atomic Speed bundle from IndieGala around July 14, 2020. Sad to see it's not in there if the keys were revoked or compromised some other way before/after my purchase of the bundle. Not a huge deal overall, but I am kind of curious as to why it...
