How can I get title with stars??

Unlock the title again.

After you get the last title in a series for example, 1000 bootcamp cheese it will start from the beginning adding a star when you meet the requirements again. 1001 Bootcamp cheese would unlock «Rookie ★» .

^ They're faster.

TY everybody :)
