This is a bug that uses Mouse Tails (x50)
Under your Living Tab you will see the new collection quest for 50 mouse tail (1 free day of 9D Prim User)
If you do this on a lvl 1 player the reward goes to all your players.
1) Make a new player and level him to LS1
2) Get 50 Mouse Tail and use them on your Living Tab (Something (II) it is one of the new ones)
3) Turn the quest in and use the Reward that you receive that gives you 1 Day of 9D Prim User
4) Play your free day on your main player until the time runs out (24 hours from when you used it)
5) Delete your Level 1 player and start over with step 1!
Do this and stay in Prim Player as long as you have 50 Tails!
