Battle.net is being a bitch. I'll be doing very well in a match. I'll have an army of stalkers survive an attack by 2 other armies, and I go in for a counter. All of the sudden, the connection hiccups for a split second and results in my forced surrender, which goes down as a loss in my record and brings me down another grade or two. (Blizzard needs to stop being richards and start recognizing crashes as unofficial losses.
The relevance of this is that I didn't feel like playing Minecraft after that and built a bit. Doors added in a hallway. Not much, but it's still progress.
