I've had a persistent problem where the game won't let me save creatures (or even give them a name, as of this update it bugs out and deselects the whole window after the first letter now) and now the simulation becomes a blank screen and never moves on after generation 5. I've noticed the game already knows all my settings from before even after uninstalling and reinstalling, including when I tried to hunt down every file and folder named "Evolution" or "Keiwan" on my machine, and with the fresh install it doesn't even let me choose my resolution or anything any more. I feel like if I could just kill whatever old files it keeps digging up that the problem would go away but I can't seem to find them.
