When trying to connect to a Strat battle you ALWAYs have to turn you WSE2 beta off or you wont be able to connect.
Many times you will see a lot fewer servers when you are going to connect to a strat battle. This never happens unless there is a strat battle. Sometimes you get a few servers, sometimes you get none.
Sometime you can restart the client the entire strat battle and you never get access to the strat servers.
I have tried changing the settings.txt file, reparing, turning off wse2 beta, uninstall hamachi, restarting the computer, joining a native server (which works fine).
There are many that have this problem.
This only happens since the last patch.
Freaking annoying.
