I got network error in 3 battles in a row, in less than an hour, and a few more in base when trying to train troops. I'm losing resources, loot, blessings and medals. I reported the problem to cs, but I don't expect much from them. Generous compensation should be obvious in this case to all affected players.
If this is server side, then Nexon should be jumping to Amazon's throats right now until the issue is fixed.
