Small update?
 

Got a small update today when I logged in. Can't seem to find any explaination as to why, though.

Could be a minor thinbg like say a minor graphic fix or a minor security loop hole closed

Heres what I found out... When something new comes out, like a new invasion, the update the game the day BEFORE the real day it should come out. So that update was proboly the V-day shirt quest.

They update the game early in the morning when they add those.

The minor update happens from time to time, it was probably graphics like emerald suggested.

Maybe it was to confuse you Basil.
