Hmm, I'm not sure, but it's probably a bug of some kind >.< Unfortunately, all the stuff lope the settings for auto mode are all determined by Naninovel and I don't poke around with those since it's all like pre-programmed and I don't wanna break anything >.< Naninovel has had a good few updates since I released this though, so it's possible that if it was a bug there, they might've fixed that now, so the next time I load up this project to work on a new episode, I should be able to update it to the most recent version of Naninovel, and with any luck, it might work a bit better, haha.
Glad you've been having fun with it anyhow! Hope you get to have happy holidays :3
