The browser version just has an empty box instead of showing the stats for me.
Which browser/OS are you using?
Interesting, that's what I test on! Regardless, thanks for the report, I'll look into it a bit more and see if there's anything I can try in the next update.
I have the same. on win7 and opera. after playing 100 days I just discovered that statistics should be displayed when I looked on the forum.
