An update was released today that contains some game memory optimizations. This should result in fewer game crashes due to 'Out of available handles'.
The game launcher has also been updated with some bugfixes and optimizations. Fatal errors will now show a dialog with the error message. Fixed some bugs preventing people from running the launcher. Downloading and patching the game should be much quicker now. A progress bar for downloading the game and uploading crash dumps has been added. We've integrated a new crash dump reporting system so that we can more easily track and analyze game crashes.
