Fullscreen and resolutions seem to be pushing people's computers to the limits. Playing in a windowed resolution seems to be the stable choice, but I've had some even report the opposite. Looking into any overarching performance issues that I can address.
Surrendering multiple times is a silly thing you can do right now, which might even load up more than one instance of text (causing the game to freak out and persist it) - a fresh reload of the whole game will do nicely for now. This is fixed, and is one of the many things waiting for a release in the next - hopefully more stable - update.
