THERE IS A WAY TO FIX Confirmation of Changes: Session Lost!!!!! my buddy Fyreffect told me to do this. 1. go to your steam library 2. right click Dayz on the left of your screen (listed with your other games) 3. click "Properties" down at the bottom 4. when the screen pops up go to the "Local Files" tab second to last from the right 5. click the option " Verify Integrity of Game Cache" 6. it will validate. and will replace any missing files of the game. i was missing 5 files. did this and no more "Confirmation of Changes Session Lost" message for me!!!!! i am not sure if this works for the other messages, nor i dont know if i jus got lucky n it started working. all i know is that i am at NWAF looting the ♥♥♥♥ up. PLEASE PASS THIS ON TO OTHER FORUMS SO PEOPLE CAN PLAY and give "Fyreffect" the ♥♥♥♥in shoutout!
