I believe this has been happening since I installed v.18.0.6.
If I add a product (Line Items > Add New Item) to an order which is allocated to a customer's account, the order is subsequently unallocated from the customer's account. I am then able to re-allocate it, but obviously I don't think it should be unallocating it in the first place. I have never had this happen in the past.
