My Logs For Yesterday Disappeared

It shows up in the reports, the calendar, but when clicking on the log itself I just get a blank screen. Any idea where it went? It was there yesterday.

You have some weird garbage character in the zone name for The Thousands Maws of Toto-Rak that is causing the JSON to not be valid. Never seen that before.

Is there a way to go in and fix the JSON? I see it (in 10 places) now in the returned JSON.
