Civ games have always had excellent post-release support, so I wouldn't worry too much about minor bugs. They'll likely get squashed.
As for the victory odds thing, I don't mind it because it's very inaccurate. If it says "decisive" in either direction you'll probably meet the right overall result, but anything less than that there's no guarantee at all. I've won a battle listed as "major defeat" and I've lost battles that the pop-up said I'd win. The random number generator certainly plays into that, but I also suspect it doesn't take certain bonuses into account, for instance if you have the policy that makes your troops more effective against barbarians or on their own soil.
The big surprise last night: Barbarians can, and will, steal your workers. I had "freed" quite a few workers from city-states when busting up barbarian camps (whether I gave them back or kept them depended on how I felt about that particular city-state) but was still surprised when they took one of mine.
It was actually a nice move by the AI. I was moving a warrior unit and an archer unit to smash a barbarian camp, which basically consisted of my entire non-scout military. On the way I passed a unit of barbarian archers from the same camp, but rather than attacking they moved out of my LOS before the next turn, so perceiving the bigger threat to be the camp and not the lone unit, I continued on instead of chasing them. So on the same turn that I was doing battle with the camp the archer unit moved in and swiped a worker while I had no way to stop them.
I peeled off my archer unit and left the warrior unit to finish the camp off by itself, so managed to pin the barbarian unit in between my city's ranged attack and my archer unit's attack, so killed them pretty easily. But my stolen workers needed to be repatriated, and ran off. I had to chase them for about 15 tiles before I was able to recapture them.
Good times.
