Yeah, there's a way to reset both maps and monsters set with "Feeling of the xxxx" and "Hatred of the xxxx".
What you need to do:
Have "Enjoyable Rest" and sit next to another TK/SG, then you start spamming /doridori command. When you /doridori you'll get the "Happy" status(an icon shows up just like any buff) and you have to continue using /doridori until your Angel appears and reset your maps and monsters.
I don't remember what's the chance of happening but I think it's 0.1% or 0.01%, something like that....
Hope I helped you, good luck
