Hi, yesterday 8-2-2014 we could not connect to tanki online, trying from 3 different PC and accounts. It was a problem with the tanki's browser. So, we could not increase the diamonts (just ~ 600-650 more)and get the discount for the railgun. Could you replay this offer ? For sure there are thousands who had the same problem. Congratulations for the game! Many thanks Zeus-fighter
