When I start building anything the building just disappears. Sometimes it disappears instantly and sometimes it goes up to 30-50% and then just disappears.

And yes I've emptied cache and everything you can on browser. Upgraded it upgraded flash etc... Tried another browser (same problem). Nothing seems to help. And it just suddenly started happening middle of a game. And yes I have the resources for building and its in correct location and It happens on every building. Also sold fev buildings but still the problem occurs.

When the "disappearing" happens. The game kinda does this laggy efect and it freezes for 1s.

win 7 chrome ( also tried with IE)
