My understanding of the cycle is this:
- An earthquake pops a Noble Dojorn which resets the 7d Noble Dojorn cycle. An earthquake will not despawn any OoAs, thus their respective 3d cycles continue.
- A server reset (like this mornings) despawns all the OoAs, and does not spawn a Noble Dojorn which does not effect the 7d cycle.
- A server reset with a patch which spawns all mobs despawns all of the OoAs, and spawns a Noble Dojorn which will reset the 7d cycle.
I could be wrong on any of these points though
