Recently, I've had a problem with my events "skipping" or just misbehaving in general. For instance, one event has your character hide under a table before the villain comes in to look for you. When she finds you, your character is supposed to jump out from under the table so you can continue running. However, at this point, the game plays the door sound effect that was present near the beginning, sets the villain to continue chasing you, and then makes you reappear, which often causes problems when you pop up right next to her.
I'm sorry if this sounds vague, and I'm also sorry I can't show a specific example. (The universe seems hell-bent on not letting me record my problem...) More than anything, I just want to know if there are any general problems that could cause this kind of behavior. My friend has suggested that I might be overloading the engine because I have a few other common events running in the background, as well.
