This may already be too late, but for the rest of you... Please try using regular names (ie. use character a-z A-Z, and numbers only). For your Battle of Saratoga file, you have 4 items with invalid name. It may not be your fault, maybe Alice messed up while saving your file.
Open the attached file and please make the necessary modification to your code. There is a whole bunch of null where your 4 items used to be. Please post what are the missing items so others know not to make the same mistake next time. Thanks.
