There appears to be an issue with Guild Wars failing to lock the friendship to the one at time of posting defense. Here is my defense lineups, not altered for nearly a week.
Note Felix has Frozone power. I would add… this was against going Going Turbo which is why you see so many clean sweeps.
Here is my defense result.
As you can see Felix has the Ralph power. I use Felix Ra for blue invasion, hence it would have been the active power on current settings. However, as you can see, the Guild War had it posted with Fr… and still does shiw Fr. It appears that at the time War commenced it locked on to my current settings and not my War defense team.
I suspect it might be to do with my ranking him up during invasion… so perhaps the game was trying to give me the benefit of that ranking up. However, changing his power fundamentally undermines the point of him being in that defense lineup.
