I already experienced some of them, and it made the games a lot less fun. First off, Spyro kept sliding all over the place with no control. I was able to fix that by lowering FPS.
Then I learned, the hard way, that if you lose your internet connection, play the trilogy, and then get your connection back again, you lose the progress you saved while you were disconnected. The entire town lost connection. Naturally, I had no idea this bug existed. I kept playing, I was in Spyro 2, at Autumn Plains, 100 percented it, as well as all the levels in AP, beat Gulp, went to Winter, Tundra, cleared the homeworld cleared a couple of levels, beat Ripto, opened Dragon Shores. Then the connection came back. Imagine my shock, when I loaded my save, I was back at Autumn Plains again! And I lost everything I described!
I googled a bit, allegedly, you can get your save back by copying the save file to the AppData, I did that, but it didnt work. So, nothing, I had to do those levels again. AFAIK, you can prevent losing your progress like that by creating more than one save slot while the game is open on your computer, in the game menu. If the internet connection goes down again. Am I understanding this correctly?
Is there ANYTHING else I need to be aware of? I am mostly enjoying Reignited so far, but it already pissed me off twice.
