Nope, fresh from scratch.
The bug happen when I push mouse wheel up to go back to previous. I would probably try again in the next update, would you add cheat mode in the future update to save us some time?
Ah, ok, I've seen that too. It's happened to me when you enter a scene, and either you start a conversation with someone but don't finish it or there's an automatic event, and you try to use the mouse wheel to go back. I assumed that it was kind of a didn't-reach-a-code-checkpoint kind of problem rather than a bug.
I think you can avoid it by starting the conversation with the person, ending it immediately, then talking to them again. I'm not sure you can do anything about automatic events, just let them play out.
