I ended up in a hacked server. One of the hacks was - if you die by your own hand (such as falling off a skyscraper in my case) your rank (at your current prestige level) becomes 70.
While this is advantagous in that it partially unlocked things I wanted (ninja pro, claymores) so that I could earn them. It means that a) I'm not earning xp as I play and b) I am level 70 without things fully unlocked.
(When I refer to 'partially' and 'fully' I mean that a partially unlocked thing means I still have to complete a challenge to get it, but it is 'unlocked' for my level. Fully unlocked means I have it. I can use it)
Is there a way to restore my account back to where it was (about level 15 third prestige)
