We were playing really nice matches tonight, but at the last battle - where we destroyed Germans - the game bugged and said we lost (despite having +50 tickets), since it was the last objective we lost the whole campaign and I heard that if would've won this battle the whole campaign would be won (Germans had very few attack power, fewer than us)... I wouldn't complain if Germans beat us and claim victory, but ending campaign like that was a serious letdown...
I also tried the multiplayer campaign recently, and I got a bit embarrassed on behalf of TWI, since the end-of-round bug kept kicking in almost every round, giving victory to both teams at once, and all the beginners (and not a few veterans as well) were completely baffled, and I understand them.
It is such a drag having a good game where the team is really fighting and giving its best, and it is always close games this occurs on, since the bug only kicks in when both teams are out of reinforcements, then to see that the game awards an undeserved victory to the other team as well.
Although present in the game since release this bug has managed to stay relatively unnoticed by many, I still hear veterans that claim they have never experienced it before when they encounter it now, but with the multiplayer campaign it suddenly becomes very noticeable, since the victory awards is rather important there. The bug has been reported several times (as in the link in my sig) and has also been acknowledged by TWI on at least one occasion, but unfortunately it doesn't seem to have been prioritised. Hopefully it will be now.
