The entrance to the Void Brothel is broken, the NPC says enjoy your time but the gate doesn´t open
Searched for any way that could trigger this bug. I found one possible explanation. Last visit, you might have used a teleporting item instead of using the regular exit, which makes the event lock itself. Upon entering the lobby and exiting again it resets and fixes it. I will create a solution for it, but if you think it might have happened any other way, do let me know.
