This is how it works for us:
If you are in an encounter and go to "Orders" and then choose "Save (but don't send)", it prints the orders in the "Plan" portion of the encounter. I think this is how it should work.
If you are in a message and go to "Orders" and then choose "Save (but don't send)",....it seems to delete the orders AND the content of the message, and the orders are not saved anywhere.
You might think that is a bug, but I don't think so...if you are in a message, you are, by definition SENDING the orders. The solution is to NEVER hit "Save (but don't send)" when you are in a message. ALWAYS use "Send" when you are in a message, and the order will appear in the message.
Did that address your issue, Sky?
