Game brings my computer to a halt after being open for around 30-60 minutes.

Since the version 4.0 update the game brings my computer to a screeching halt after about 30-60 of being open. Not even playing, just being open. The dock becomes unresponsive and Plex starts to stutter. I have to Force Quit it. Lots of people have said on the forums they have the same issue. When I tried to discuss it on Z2’s forums they banned my ability to post on the forums.

I have a i5 and 16GB of RAM so my computer should not be the issue.
