Hi, don't kill me if it's not the right place where to write, i just don't know where else.
During the latest version a pretty annoying bug raised (don't get me wrong I think this is one of the better maintained browser game i ever played and enjoyed):
the mouse suddenly disappear when an advertisement appear. the only fix i have found is to close the tab and open another, but this is sometimes fatal with strict boot timings.
i am on last OSX and Chrome browser with no plugins. it happens both on full screen and normal one.
it happens for sure when an ads appear and i am typing in the chat but often also during normal gameplay.
i've heard a lot of player having this problem. if i catch more info ill write them down.
