I recently started to play this game again but on a new account because I had done pretty much everything on my old account and I got the character the Tank Commander, who I love and I tried to max him out but when I got him to the super elite rank his level was 0. I was confused when I saw 0 and tried to level him up but it said I leveled up to level -1 and then imminently put me back at 0. when I was playing multiplayer he leveled up to level 1 but when I went back to the backyard he was back at level 0. how can I make my tank commander go up levels and for the levels to not go away in multiplayer?
