That code just triggers the scene that starts Erin's peeking events. It will take effect after you finish a training session with Cecille.
But each time you input it in the console it duplicates the trigger. Once is enough.
I'm not sure where you're stuck. This code only applies if you haven't seen the Erin peeking scenes.
If you did and can't progress then you have to finish the Lavinia side events in the afternoon (reading book, dates)
i'm stuck at the part after finishing all the dates after meeting the generals and you do a show for the demons with elena and you have taken sera's virginity and the most recent thing i have passed is the demon king saying he's intrigued by elena and wants to meet her and mars say he needs to think about it i'm stuck from there i don't know what to do to set in the next scene and i have also done the femdon erin training with elena already it just says more will be added next update
but then is there a reason i can't finish the maid training or is that all there is upto in this update? if not then i can't activate the erin peeking scene without completing the maid scene correct or am i wrong also i'm stuck at 52 affection with her is there a bug maybe or somehow to increase it
