I was getting similar on Lakeville yesterday.
And people in chat out of battle were mentioning similar on random maps all day, so wouldnt surprise me if its server side stuff the mad russians are up to.
Oh and I wants a HEAVY tank. Saw a few yesterday and WOWEE am I impressed.
My biggest gripe with WoT is the 15 v 15, I want larger battles, dont get me wrong 30 in a game can still be epic, but I want a Kursk!!!
