I had something similar happen to me - I played during the server issues a few days back (which I mistook for temporarily slow internet, which happens to me a lot) and my final battle of the day on Thursday (a loss) wasn’t counted. I didn’t mind that much, but on Friday, my first fight of the day was the Paragon fight, which I won, but then it bugged out, saying it couldn’t find an opponent.
Since then, every time I log in on my main account (I have multiple, I’m slightly obsessed) it says “Internal error” before the map loads, and then crashes when I try to enter my guild. It will also crash occasionally upon clicking on the troop or chest menu, and sometimes just because. I was able to get a few explores in last night, but not more than that.
I’ve sent a support ticket but I know it’s the weekend and probably won’t be seen until tomorrow. I’m hoping it gets fixed soon, I’m a guild leader that kinda wants to help out on the new modes coming.
