The json files are corrupted.

I tried to open it in R, I got this error:

Error in parse_con(txt, bigint_as_char) : parse error: trailing garbage
":1,"gamestate_id":4687346} {"player":{"hand":[{"attack":4,
                      (right here) ------^

I pick a small portion (5 gamestate_IDs) of the file and try to view it with "http://www.jsoneditoronline.org/" I got similar error:

Error: Parse error on line 1:
...state_id":4687346}
{"player":{"hand":[{
----------------------^
Expecting 'EOF', '}', ',', ']', got '{'

I opened the same file in Tableau, it only shows the first gamestate.
It seems that between the first gamestate_id and the second one there should be a special charechter that is missed.
