I have a problem with a mission "Sneak into underground brothel to obtain confidential information" on 6/12 friday when MC get's called during dinner. I go to the passage to the lower side of the city where brothel is with Alice and redhead dude i forgot the name of but there is a guard and he asks me for a passport, then MC says "If it weren't for the mission, why would I bother going to the underground street" and there is no further action to take, next to the guard is debris on both of his sides so I can't go past him. I searched for something to let me go down but I can't find anything. I don't know if it's bugged or am I searching in a wrong place?
