When one goes to add a payment to an Advanced Sales order they will notice that the payment method of "other" is not an option. One will go to Tickets > Sales Methods > Advanced sales and see active other payment options available. Another similar issue is in Sales > Unresolved Online Sales, the Other button shows but does not have any other methods to select.
This issue was resolved in Altru version 3.19. All sites should have been upgraded November 2014.
