Hi everyone. I just wanted to step in and let you know that we are actively investigating reports of this issue still existing on the Tomb of Freedon Nadd server since the 1.6.2 patch. If you are still experiencing this and are on a different server, please post here and let us know. As more information becomes available, we will update this thread and/or the Known Issues. Thanks for your patience!
It's still happening on red eclipse as well, but only 1-2 of the prisoners in each group so it's easy to work around by simply going to 2 different groups to get the total you need.
