it actually works fine here's a tip use his 55k trainer so when u use the combat record editor and your finished using it. Use the 55k Trainer then play a match and you will level up and keep the changes.
This made me reset from my last save.
I was at level 21, prestige 1.
After I used the Combat Record trainer, I went off and later I went back in and got a message saying my data got corrupted and I got reset to Level 55 Commander.
