As of today, we officially know that you have messed up dimensional raid. The server opening hour has been brought back 2 hours and it is up as we speak. However you did not consider to change the NPC spawn time, resulting in another of the many awkward situations of people waiting for nothing...
My guess is the NPCs will spawn 2 hours later, when the server will have closed of course.
Waiting for your reply.
Cheers!
