I can’t even get into a game, getting backend errors every time I load into the keep. I think it could be a problem with the chests, I opened (I thought) all of my chests, and then remember seeing that I didn’t open one after leaving the menu, so I opened it. Wondering if that could be the cause.
Is there any more information or a number accompanying the error? A screenshot would be handy. 
I was able to play a couple games last night. Not sure what was causing the backend errors, but I’ll make sure to get an error code if it pops up again.
