Use search, I've created a
bundle (swf games and game endings playing with Flash Player standalone) where this problem was fixed few years ago.
You must be registered to see the links
to bundle's cloud.
There are very little content (only 1st 12 days, very little amount of porn and some scenes have errors and shows black screen due missing images or some content not rendered yet). Good thing that game engine now is RenPy with all cons it gives comparing to Unity so I advice bettter to wait until release.
Here is it but wouldn't answer any question about game errors (better adress it to developer). Use it on own risk and don't ping me plz.
