There isn't enough information for me to understand what the problem is. Could you explain in more detail?
For example, Tantalus is group leader. We have 12 in our raid group. I tried to start Helegrod Drake Wing at level 85. Nothing happens becausd Player 8 goes link dead (client crashes to desktop) when they try to enter the instance.
Turbine will need detailed information in order to reproduce the problem. Otherwise, fixing it is not possible. That happens with software. There is clearly something wrong. I have no clue what the customer is doing or seeing. Something like "Feature A is broke" for a complaint does not do anything.
Or in my own personal life. Ms. Yula calls on the cell phone. Come out and change my tire. Where are you? I do not know. Honey are you in Palm Beach County?
