Editing the save file can print invalid lists. Could pass the ID number and print it out instead of having ID_0001 as a string only. If there are any errors in the file format, can skip the line of data instead rather than to print it out.

Similarly for this, the input given contains a non-digit and the program crashes. An exception should be thrown to ignore the line of data if it is unable to be parsed.
