Greetings everyone,
As a precaution we have increased the time it takes to log out of the game within safe areas if you have a pet, mounted or otherwise, in the world in an attempt to resolve the pet disappearing issue.
We have received several pages regarding this, and it is by design. If you receive there is another character in the world message, please give it a few moments and try again.
Have a great day,
Mesanna
