Sorry if this is the wrong place for this kind of bug report, but this forum really doesn't seem to have a clear-cut "Bug reporting" section. I guess this game is well-developed enough not to need it.
I'll admit, Sins took way longer to present a bug to me than most games, I'm surprised. Actually, this "bug" may, though I doubt it, be intended (as one of my regular opponents, who does not play Advent, suggested), but it's really annoying.
Anyway, here's the point. The Rapture Battlecruiser's "Domination" power causes an interesting problem if you target an enemy Crusader with it... You get the cruiser, but if it has the "Ruthlessness" upgrade your (the owner of the Rapture) ships still take damage from the Ruthlessness while the ships of the previous owner do not. This extends to damaging the source of the Ruthlessness as well. If this is intended or has already been successfully dealt with for a future update, please let me know - whether or not I can safely steal my opponents' Crusdaders in my local (Advent-dominated) play pool will make a difference.
Oh, and the damage does make a significant difference if you grab multiple Crusaders, as my Guardians seem to enjoy absorbing the damage for everyone. I had several mind-controlled Crusaders and they wiped out my four Guardians when I wasn't watching. (This was before I realized what was causing the damage)
