I'm in tier7 now. Yesterdday I found that when I level-up in tier mode, the tier points of each mission will not reset if I quit the game after I level up. The weird point is when I check my map immediately after I level-up, the tier point of each missions are resetted, but if I quit the game, re-lunch the game and check again, the tier poind reduced to the un-resetted level. I met this bug twice when I up to tier8 and tier7. With this bug, I think I'll never be able to reach tier1...Does anyone meet the same bug with me? Does anyone know how to fix it?

ps: I found the same bug in Known Issue list and it said this bug is fixed in TU7. However with the latest update I still meet this bug.
