Yes. your existing save file when you were first trying to get kuri done is ruined. Like I sort of explained before, when you had a quest lined up for there at that time and talked to Kuri, it cycled through all of your quest and gave you the lowest one instead of the 1st one in call. I did not know the engine does this. I have changed it where you have to click an option for the game to give you a flag. I can fix your save file if you'd like, but if you want to wait a while before playing again, totally understandable.
In order to get kuri to show up, all you need to do is go to a shop or the gym, learn you need money, go talk to zorro, sell him something, then Kuri introduction option of being thirsty will appear in the park in the afternoon. This has always worked. The problem before was I did not know that the engine called up all the events that are to take place when you're on multiple quest.
And thanks for telling about the gorilla event, it shouldn't be in there and i don't know how it got in there.
