Once unstickied, this thread will be integrated in the FAQ (wiki tab on top of the subreddit's frontpage/hot). Right now the popularity of the game has exploded because of the 'On the House' Origin deal, and I sense that compatibility and bugs are the most important current matter to deal with.
It will be indefinitely stickied until something more important needs attention. Greetings and welcome to the subreddit! This is a post that I will try to keep constantly updated with various resources for fixing compatibility issues and bugs.
