AQ Failed! Log out!! [AQType: 5]

Hey Elitepvpers,

i have a bug with my pets. Everytime i try to activate a grabpet or another pet
i get disconnected from my server. The gameserver is giving me this error:
AQ Failed! Log out!! [AQType: 5]

It looks like you have a problem with _AddNewCOS if i'm not mistaken. Take a look into it.
