I have added a number of hop variety's into my inventory with no vendor attached. For example "Cascade hops 7AA 2 oz" I find that when I have formulated a recipe, saved it and then reopened it later to edit, the software has added a vendor to the hop. In my example it might change my recipe entry to this -- "Northern Brewer Cascade 7AA 2oz" This can get very confusing and I have to go back and re-enter the hops. What gives? Have I done something wrong in the inventory?
