Had a small power outage/surge tonight from the weather while I was running the game and my PC turned off, when I started the game back up the window size/position was set to what seemed to be 0,0,0,0. Minor inconvenience/annoyance, was able to right-click > window size/location to restore it. Unsure if this occurs when powering off regularly (holding power button, or whatever) or is a one time occurrence.
