For almost all the vehicles I have used I have experienced that the web version of battlelog is out of sync with the in-game situation. Progression is correct in-game and I can equip the stuff I have unlocked. However in the web version it seems to be lagging several unlocks behind. I cannot change the loadout of the vehicles and service stars do not show up correctly. If I change the loadout in-game, the loadout show up correctly on the web, even though the unlock progression claims that I have not yet unlocked the stuff I have equipped.
In the beginning the unlock progression is correct, but then suddenly web battlelog "snaps" back to an earlier progression level and keeps lagging behind.
Example: The loadout screen correctly displays that "Active Protection" for attack boats is equipped, but the unlock list shows that I'm only about 1/3 into "Laser Guided". If I click on Active Protection in the loadout screen, it will show it as equipped even though it is not unlocked yet 8which is incorrect).
I have similar problem and I suspect that it may have something to do with XP multipliers. Currently we have XP x2 and it looks like client side (ps3) is counting as x2, but servers/battlelog counts as x1?
Of course I don't know exact reason. Could you confirm if it could have something to do with XP multipliers?
I'm also seeing this issue. I'm a PS4 player and Battlelog in a web browser and also on my Android app appear to be showing inaccurate unlocks. It seems that it kept track of things correctly until a 1-3 weeks ago. After that point, all of my unlocks don't register (in fact, I have unlocked all vehicle items and they work in-game, they just don't show up correctly here).
