Game error in characters

Hello, I have an account on Warmane called Kziq, and on the account I have a character named the same way. I began a trip on a hippogriff from the south of the eastern kingdoms, towards the kingdom of the dwarves, and while I was making the trip, the internet in my home was disconnected. When I started the game again, my character was flying with the hippogriff below the ground and within the mountains in a clear system error, the character makes this round trip all the time between the wetlands and the Arathi highlands in an infinite loop. How can this error be fixed? Thank you so much.
