Pet Battle Disconnect

[Kublai-zuljin]

For me (and others as well) the disconnect only happens when starting the battle while mounted:

Disconnected after engaging in a Pet Battle

Currently, every time I try to engage in a Pet Battle, the game freezes then suddenly disconnects me. I have only tested this in Elwynn Forest and am unsure if the whole game is affected. Error code WOW51900319 UPDATE: Found a workaround. I can easily enter Pet Battles when I’m not mounted. But if I click the enemy Pet while I’m mounted, it always disconnects.
