Multiple SGF files with identical GN properties causes an error #26

Closed dormerod closed 8 years ago

dormerod commented 8 years ago

If book_gen.js is run on multiple SGFs (e.g. within a directory), and any of them have duplicate GN properties, it causes an error with the following output:

/gpub/src/glift/glift_combined.js:8047
    return this.node().properties();
                      ^
TypeError: Cannot read property 'properties' of null

Note that this doesn't happen when GN is null in multiple files.
