Aurora seems to be creating files at c:\, specifically, a "Logs" folder with a subfolder for each of my games and a bunch of text files that contain event data, including that on alien races I can't see as a player. (i.e, reports on alien shipyards adding new slips, etc.)
The game itself is installed quite a few folders deep on the c:\ drive. I have no idea why it's creating logs at the root all of a sudden.
I'm not sure if this is a "bug" or a "new user question", so I figured I'd post it here.
