[PS3] BF4 Classes are reset and all my unlocks are relocked. Please Fix!

You could try this:

[Battlefield 4 players are reporting that they've lost access to their previously unlocked game content, such as weapons, attachments, and more.

Some of these players have reported success into logging into Battlelog and saving their Loadouts to correct the issue.

If you've been affected and your unlocks are missing, rest assured that we're investigating this issue and will provide updates as quickly as possible].

XP=thanks for helping 

Same issue. Xbox 360, tried going to battlelog and saving a new loadout, didn't work.

It's happening to me too. all my unlock are all locked again. It really damn annoying that EA would release a unfinished game. I've tried all of these things and nothing has changed. I got it for the 360

This works! 😕mileyvery-happy:

Going to Battlelog and changing my loadout worked once for me.  Since then the  same problems came back and I tried a loadout change on both the computer and I phone and it wouldn't work for me.  Please help! 

This is also happening to me it is only with few servers i get my stuff back i cant even level up there is no point in me playing this and right now im contacting EA this is the fifth time i contacted them about this SO ANNOYING

It happened to me on PS3 too. Not on PS4.

A bigger issue to be aware for upgrading to PS4 tho. I lost all unlocks from Appreciation Month that I unlocked on my PS3.

This just happens sometimes.I later found out that it's the server settings itself.Whoever made the server probably set it to defaults only.I once joined a server and found everyone running around with default weapons.
