Having trouble with logged position in Dayz, since the last patch which added zed flashlights.
1 log out,
2 wait 15 seconds.
3 turn off console
4 turn on console and log in
5 position/ time logged in is previous/ not the same to actual logged out position, by about 3-5 minutes of game play

I log back in to a position I was previously at. If inventory managing, or picking up inventory before the log, I sometimes don’t have that inventory, I.e it despawns/ I haven’t picked it up, etc.
