and that wasn't true even with the old lobby. The separate lobby "servers" each synchronized with eachother a few times per hour, so they theoretically had the same data.
I believe that up until 1.4, Soldat used the data from one server anyway, the first one to respond. The lobby server architecture in 1.4 has changed completely and you should see all of the servers running, all of the time (once one or two bugs are worked out in the 1.4 patch)
