The game constantly appears to lose partial sync with the server resulting in the character being trapped in an invisible fence as the world stops responding. Positional data and group status appear in effected as when I log out andog back in I am in almost the exact same place I logged out from.
Sometimes logging off the character and logging back in works. Other times I need to log out of the game completely.
Never encountered this behavior before S4.
Yes, all software and firmware is running on the latest code version available.
