This is probably caused by the newly introduced header changes.
Parsing fails at:
& should be escaped while writing XML (& is a special character), but this is not done when making the replay.
This is a saving failure at Nadeo's side, and because of this, reading can not be done properly.
I have reported this bug to Nadeo.
Another replay, which was correctly submitted on one of his maps, contains this header:
It doesn't seem to have author zone information in it, so the & symbol isn't written at all, as a result, it can properly be parsed.
