Battlefield 4 Campaign Bug Kunlun Mountains Bug

Having the same Problem, i replay the mission 3 times, but the last dogtag now is missing.

The last Dogtag under the Bridge is now hidden/disappear!!!

Please Fix this, its my last Dogtag to become the related Trophies!

I do have this problem as well. Kindof. I have a download from PSN version of BF4 for PS3. The problem I have is that the second dogtag collectible in Kunlun Mountains single player mission (dogtag name is Freedom at any Cost) is not registering. I can pick it up inside level ok, but the collectible count fort Kunlun does not increase by one as it should and also the appropriate multiplayer dogtag is not being unlocked. It is possible to pick up the dogtag as many times as I restart the mission, so it seems that the game does not register the action of picking the item from the wall. So far I have experimented with this on "easy" difficulty level only. This dogtag is last collectible I need to pick up for the "Full arsenal" trophy and sadly it seems that it can not be done at the moment.

I have the same problem collecting this dog tag, and I have tried it on new saves with and without the 1.02 patch. I was also missing the campaign medal for sacrifising Hannah in the final missiion. I think both of these are stopping me getting the Full arsenal trophy.

Yep on further inspection the first two are there but do not disappear when collecting them and the last one is just gone.

Same problem here on the XBOX, all of the tags show up for me and allow me to pick them up again except it doesn't give me credit for picking up the tag. Says I've only picked up 2 of 3 tags. I've played through the mission 3 times as well. Same result each time too.

Had this issue on Several Campaign Missions on the 360.  The DogTags were unlocked for use in MP, but I did NOT get credit for picking them up in the Campaign.  

At least your whole Campaign saves haven't just dissapeared like mine on 360
