We were notified of an issue with the tail of the Dire Wolf that caused it to experience a run time error (out of memory) and then the tail would becoming unresponsive.  To address this, our scripter has split the Tail’s script into two so they separately handle the tail functions (positions, wags, etc) and another script handles the Dire’s special functions (Recolor, etc).  If you have the Dire Wolf avatar, you can use the updater that comes with the avatar to get the update.
