Ever since the upgrade this past December where they added new attractions and research rides that can be bought with coins, I have been having continual problems with my settings shutting themselves off. I'll be playing the game and all of a sudden, the sound effects stop working, or the music stops playing. I go to the settings tab and those corresponding boxes have been unchecked. I recheck so that all have check marks. Then, after awhile, the same thing happens and I have to go to settings to fix again. Is this a bug with the update? This never happened to me before I upgraded. Thanks for letting me know if there's a fix for this.
