Save OTS as in Quote Entry generates error if not "None"

Got a customer on 10.2.100 in Quote Entry. She uses One-Time ShipTo for a LOT of her quotes and orders, and in Quote Entry and Order Entry she can check the OTS box and enter the address, and on each Customer record she can select Allow OTS and Save OTS As "ShipTo.

HOWEVER, on both Quote Entry and Order Entry, if you have anything other than “NONE” in the Save OTS As box on the One Time ShipTo screen, you get the “object reference not set to an instance of an object” error. As you can imagine, the shipto does not get saved.

Anyone else run into this, and is it something I need to call in for?
