I just noticed this in one of my games. Game 41232 (Crom vs Guest). It's a 4v4 game.
If I look in the battle report for my team I see at least 1 missing battle.
This turn (18) I see one combat for my team mate Magian (he took over a gold site)
Last turn (17) I see 2 combats for my team mate Magian (he took over a gold site and conquered a city)
What's missing is the fact he also searched a L3 ruin. That ruin was right beside the city and gold site he conquered on turn 17. When I look in the History report (that shows the reward he gets) I don't see it there either. It's as if a L3 ruin search isn't making it into Battle Report/History.
