Yes, that is correct. Also, I don't remember the ranks specifically, however, I'll try to be as accurate as possible. CrimsonSkorpo's highest rank solider was 47-48 and had 6-7 unlocked soldiers all together I believe xXchaosbranXx's highest rank was 24-25 (no other soldiers were unlocked). The Current highest rank from CRAZYCAPRICORN93 is 44 and has 5 unlocked soldiers altogether. Also the date that this occurred was either in the 15th or the 16th of February and has been that way ever since.
We are aware that some players are experiencing a copying issue while playing split-screen/sharing console and Infinity Ward is investigating. In the mean time, try playing an online match and see if your stats return to normal as well as logging all accounts out of the console and clearing the cache. Please keep us posted on the results.
Can you please private message me the following information so that I can escalate your request for stat restoration?
