If you played our game on an Android phone on Monday then you probably noticed a pop-up saying nothing more than "test". This was part of routine testing and was intended to go to a small internal audience, but was inadvertently sent much wider. This message also caused the client to crash due to it not containing the correct URL data when you tapped the message (like sending you to Guild Events page). Mostly we wanted to assure everyone that there was no malicious activity that caused this issue, but rather a box that was checked that shouldn't have been.
We apologize for the inconvenience.
