I never played that game in any way possible. The log shows that I attacked his player with my bard on the first turn after sprinting. I didn't think a unit could move from start spot to opponent's start area. Then after attacking I surrendered. I repeat, I never entered that game until after it was over. I bought this game yesterday, and already been cheated or bugged in 2 out of 6 games. The other 4 I lost fairly, I am assuming they would have cheated also if I was winning.
I'm not exactly sure what happened here. Definitely a glitch of some sort. The bard sprinted then appears to have attacked twice. I can vouch for the opponent though. He is a top notch player and wouldn't need to resort to any exploits to win. Whatever happened he had nothing to do with it.
I can also assure you that in the 500 plus games I've played I never had that happen to me. While it's no doubt frustrating, the glitch you've highlighted is something ultra rare that I've never seen before. I have had other glitches happen of a different nature however.
