Sorry but it seems some bugs occur after the recent update, the quality overlay doesn't show up and the debug log keeps jumping red warnings like these. This bug happens to all of my old saves, but doesn't show up if I start a new save.

Exception in UIRootUpdate: System.ArgumentOutOfRangeException: Count must be in the range of 0 to 1023.
