So we just pushed out an update which should make things run much, much smoother for people, and fix a lot of crashes.
Now, it's not a fix-all by any means... Please don't mistake it for that... But it's the first step in our headlong dive into optimization, stabilization and overall improvement of the game's performance. I hope that it makes the game a bit more of a pleasant play experience for you all!
More updates will be coming. I realised that I'm spending more time on the discussion boards and forums than I am writing code, so I'm pacing myself a bit more. Sorry if I take longer to get back to you, but I will eventually! I'm just sure you can all agree that getting the game working and looking as best as possible is a pretty high priority right now!
