RED mob spawn times/channels?

If fields 1-6 are considered one area altogether, you're correct.

If you come back 3h later to ch17, the monster will spawn wherever there is someone in the map. If you're alone in that ch, it will spawn in your map. If there's more people, it will be a random map which has someone in it.

Thanks for your help=] now my addiction to getting boxes grows even stronger T_T
