Leaving Valdrakken too fast towards and flying towards the South Gate area (just south of the city), especially around [24.2, 71.3] of Thaldraszus has suddenly started to cause huge amounts of lag. Game stops responding to commands but allows incoming and outgoing chat, eventually it freezes and you are forced to close it down.
It is the third time this evening that it has happened to me. Each time a random number of my addons had its settings completely reset as well. Leaving the city in any other random direction causes no issues at all.
Also flying into the Zaralek Caverns tunnel from the direction of Azure Span results in this. The game becomes completely unresponsive and gives you a hard time trying to log back in after a forced shutdown.
