Hello Ryen, I am having problems with Sandra's events as I am not able to proceed, it maybe because I had done her casino event before her dungeon. If so what should I do?
If the game allows you to do things out of order, than it usually means that the order is not important to advance the events. Have you checked the next steps of her character event sequence? Maybe your main story is not advanced far enough yet.
I had reached the last chance storyline and the only reply she is giving is about the treasure we had gotten from her dungeon, I had even done her beach scene as well.
