I'm trying to use "save frame position" under the storyboard object to save a screen state. Originally this was going to only save when the player walks off-screen, to re-load later, but when I encountered this bug I mapped f5 to save and f6 to load to test more closely.
If I keep jamming f5 repeatedly, every one out of three or four tries will fail with the message "an error has occurred while writing the file." It seems to be totally at random, but this is a very complex engine and there's all sorts of things going on in the background constantly. I can't really identify any specific cause.
Does anyone have experience using this feature, or has anyone encountered this error before?
