I've played over a thousand games, pretty consistently over the past 8 months -- without any connection issues whatsoever -- and in the last week I've experienced a new issue: occasionally decisions will take a long time to resolve. During that time the client is completely unresponsive. It won't register new chat messages from either party.
I have not been able to determine if this problem is just on my side, but if so, I'm not sure what would have changed in the past week.
Has anyone else experienced this?
