Encountered a bug that prevented me from advancing the Mario quest and the related quests. I met Sophia and agreed to help her by gathering evidence myself, and Emma agreed to take down Mario. I then betrayed her by telling Mario and he gave me money. I did not receive the guest room key or any shack in the woods. I was in the process of corrupting Katarina and Emma, but I've been visiting them for weeks without any progress. Sophia is not at the gas station, and there are no updates in the quest log. It just says to meet Sophia at the gas station with evidence and corrupt Katarina / Emma. Unfortunate that I got locked out of all these characters.
