Are you playing on joiplay or PC?
PC
If you haven't seen Erin's peeking scenes you're probably soft locked. Use this command on the console (shift+o):
sum_event_bag_prio.append("p_sum_1_sp_2")
Train with Cecille after you input the command. No need to do it more than once.
Oh yea, thx a lot, it helped
