Quite an annoying bug this:
I'fe been trying to enter into a co-op battle. 2 other players where there, 1 of which loaded really slow initially, then pretty much stopped loading at about 75%
(me and the other guy were already 100% loaded).
after a while, the other (100%) guy dropped, and seeing as nothing was happening eventually I gave up too and reloaded. Except I was still stuck: after the game loaded, I could hear the music for you hear when loading battles etc, but my screen remains black. Tried it on 2 different browsers now, 2 computers, nothing: screen remains black, can't reconnect to battle or game in general.
Now after 20 minutes or so, I've finally been able to connect again, back in my town, to find out all my units were completely wiped out.
NOT COOL, if loading of a battle freezes, and I can't reconnect, it's not fair to just assume the entire battle is lost on my part. If anything just act like the battle never happened, no loss, no gains.
