A new patch has been rolled out this evening in the Stable Branch which should address the following issues:
[*]Memory leakage — Memory usage should now stay around 1,300MB - 1,800MB. This should also help reduce or eliminate framerate degradation that occurred on some systems.

[*]Looping background music — game should now cycle through different background mall music.
