If you keep switching games (next game) in Idlemaster theres a steam glitch where cards drop instantly.

I was able to knock out all the games I had left. If it stops working you need to restart steam and IM.
Was going to try with ASF since I dont have Steam installed. How do I make it switch to the next game? I can't type anything in the console window
