Not sure if anyone else is experiencing this.  I did a search on the thread and could not find an answer.  The game is freezing for me after a few minutes of play.  I can hear the menu sounds in the background but nothing shows on screen.  Normally I would go into a game and edit the rpg_core file with the following change to the file  
if (this._skipCount === 0) replace with if (this._skipCount < 0)
The problem is that with this game, it has a different kind of rpg_core file that doesn't have that line in it.  Any help would be appreciated.
