Non-Premium 20 player slots! FIX!

Hello! I and a friend of mine (we both werent premium) were trying some things when he was rank 1 and i was rank 2, so not so long ago, and when i tried changing players in game to 20, and we both accepted changes, it worked. So basically what i wanna say is : Non-premium members can get 20 slots.

Huh, that's a simple yet interesting way around it.
