From Gninja on the EQ2 Forums:
We will be allowing these events to continue after GU61 goes live.
We had originally planned to take them down with GU61 but in order for some of the less populated servers to complete the event we have decided to keep the event running. The merchant will remain for all servers regardless of completion or not but the ground spawns will stop spawning once the event is completed on each server respectfully (After GU61) The ground spawns will remain for servers that have not completed the event until the event is completed.
