When the game started, we got Shino on login. While still exploring the game, i went to "upgrade stars", and there you could see the "i" (information) icon. When i clicked that icon, it was written : "November Sign-In rewards" (we're talking about GNW Shino).

Now you don't see that anymore. Now it's just "Sign-in rewards".

I don't know if that's some bug, or GNW Shino will be the continued GNW ninja, since we couldn't upgrade him fully when the game started, 17th day in month.

But who knows, we'll see.
