Yes, this is very strange!
I also checked for typos and compared the Laundry's codes to the other tasks, but they're all the same... I honestly don't know what Ren'Py wants from me :')
I can send you a video recording of me going from Day 126 -128 to show that I have no problem when Laundry fails--add me on Facebook (Cecilia Sabrina Susanto), or give me your email maybe?
I do apologize for the inconvenience T_T I truly am confused
