Yes, I've discovered another one: Sand Patch Grade: Y 104: Car Switching. This is a lengthy but enjoyable service -- until the penultimate requirement. The order is to couple to four vehicles. But this cannot be completed because both couplers are locked and cannot be unlocked despite the distance between them. I've tried to complete this movement four times (just the impossible action) unsuccessfully!!!!! Has anyone been able to complete it? If so, how?????
