Is there an explanation, why the eu server is not switching? I hope that you did not mention it because I'm not a native speaker and maybe understand not everything.
When will the eu server start to switch again?
I'm from the EU and I hoped that the profit-switching happens on every of your servers.
Normally they both switch but because he is having issues with the latest code and some people having drop outs, he made the EU server steady, and left the switching code on the US server.
Once he rolls out new code, and it works as he hopes, they will both go back to the fun, I imagine.
