going to the Church of the Prohibition on the north side of Lake Liurnia and Vayk with festering fingerprints does not invade to get Grapes with fingerprints, face, the bosses are all dead in 2 locations! what the heck?
Maybe that's why it doesn't invade because the bosses are all dead. In DS3 there were no invasions if the location boss was killed, I don’t know how it is here.
