I have problem, 3 days ago I found many shiny events dens (riolu, garbodor, charizard, duralodon, etc) and I backup these saves with checkpoint to find the best set and seed (raid finder) for these pokemon, but today when I restored one of these saves and connect to internet, the pokemon in the den change, I don't know what's is the problem with that, please if you know how to keep the same pokemon in the den even if the days go by, I will always be grateful
