MWS Update 3/31 Error Code 0 Fix 4/1

@Kathykins, yah, the tuning file in question causing issues is the one that holds the "shared" vs. "not shared" values for ALL inventory type objects. It's not a refrigerator specific file, it's just a single file that lists all the different categories of inventory-storing objects, their capacity limit (if any), and whether they prolong freshness or not.
