During a timeout the client sometimes doesn’t react anymore, that is, even if the message that due to a disconnect you will soon redirected to the character selection appeared.
While you can still move the character and the chat seems to work for a while, neither the log out nor the lodge button respond, only the quit option.
The companion’s health is also affect by the delay. It stays full or empty even though the opposite is the case, not to mention any in-between state. If you log out and in again it is usually updated.
