To all the 1000's of dayz players out there getting SESSION LOST i am here to fix your problems. Ok deep breath here goes...Everyone who played in EXPERIMENTAL SERVERS have this problem SESSION LOST because we have the BAD DATA OR USING CUSTOM START UP COMMANDS E.G. in " SET LAUNCH OPTION" in steam e.g. mouseSmoothing=0 -nosplash -noPause -cpuCount=2 -maxMem-8192 -exThreads=4 FIX #1 = CLEAR Set Launch options. FIX #2 = DELETE DAYZ LOCAL CONTENT AND CHECK HARD DRIVE AND DELETE ANYTHING Dayz Related Then RESET PC Then RE DOWNLOAD GAME. FIX #3 = Dont Use TeamSpeak or Skype or Steam Call or Mumble or Ventrillo FIX #4 = Verify your Dayz Files Thru Steam seems to work for me and others! FIX #5 = you must die and lose your old gear FIX #6 = once you log onto a server laydown for 10mins to let your character marinate like a BBQ before moving. i suggest you try each tip you feel comfortable with before using the extreme delete local content
