Thanks for responding. I just figured it out. Apparently I had mistakenly set the rollback side to "Right". As I tend to click down and to the right to avoid making a choice by mistake, I would often be rolling back whenever I'd do that too far to the right. I've never used rollback side before so I had no idea that's what it did. So in conclusion, there is no issue I am experiencing with the game, using unren or otherwise. Sorry for misleading you.There is some meta-programming going on (not much, but I am generating and binding some methods at runtime) and I use a modified RenPy SDK, so it could very well be because of unren.
