Spent ~ 20 minutes trying to find the right bench in the church, while wearing the foundling jumpsuit. Fail after fail, was my 4th attempt, each sitting at a bench for 4 minutes it finally triggered. I absolutely cannot trigger the second one by the Marquard statue. I have tried standing amongst the other /worship(ers) and even stuck my face in the statue’s ■■■■. nothing. won’t trigger.
