Kingdom of Knuffel

I'm having trouble with my Knuffel lately. It takes forever to feed and play with them because the message sits at "loading" for ages, and sometimes it does that and then says "server error." Digging is equally difficult, when I click the button to dig it takes a long time to register, sometimes it just doesn't register, and sometimes it says "unknown server error." I'm really at a loss here and I was wondering if anyone else had/has this problem? And if so, do you know a way to fix it?
