So I logged out after finishing the Kul Tirans joining the alliance quest. I jumped off the boat that Jaina and Anduin are on into the water and bam I am disconnected. Now everytime I log on I fall into the water and disconnect. I turning down the graphics and I tried going out of windowed mode but for some reason this keeps happening.
That is an automated option that should move your character to a different location. If the issue persists, you might have a corrupted file and I’d try running a repair.
