I'm able to load up and play the game just fine for about 30min maybe an hour. I experience no other issues expect for at any given moment, the game will freeze and then it crashes to the desktop. No error popups, nothing. I've never had this issue with A19, I HOPE that it's just an issue with Experimental. I know my PC is a little long in the tooth, but like I said, the game does play A20 just fine until it doesn't.
I'm running a Intel i-5 -4690K @ 3.50GHZ
