Board Game Arena

Starting today I keep getting this error: Callback error: ReferenceError: ga is not defined

And then my profile link and turn based games in the top right are not there.

Sometimes refreshing or hitting back gets them to appear but the error occurs again and they disappear.

I'm on chrome.

Plead add an undo function. Sometimes the game even selects the wrong tile, different from the one you have clicked on.
