Whenever TwelveSky2 is running, gameguard causes Chrome to crash. Tabs aren't able to be opened, and settings cannot be accessed. I am writing this from Internet Explorer, so you must feel pain for me. Chrome is where I access everything while I play twelvesky2, and if you could get some kind of patch that doesn't cause gameguard to crash chrome tabs that would be great.
There was a Game Guard update today to resolve the issue with Chrome browser. You can now use Chrome while playing 12Sky2.
