(adsbygoogle = window.adsbygoogle || []).push({}); This is a problem with COWaW servers. It should be patched soon because this happend on COD4 also. If you notice that your online level has dropped the best thing to do is NOT PLAY. Quit game logout from PSN and sign back in.

This may not always work, but most of the time it does. Yesterday I noticed I dropped from level 15 to 10 and did this it was reset back to 15.

Yeah this usually works it did the same to me on COD4 for ps3 it reset when I logged out and back in
