A gps coordinate incredibly close to 0.000000 longitude is pretty suspect if you live nowhere near there. I recommend deleting that gist now since it may contain private info.
First, make sure you are on the latest app release. A small location fix was included in the last one which I do not think matters here, but it also includes a helpful log to confirm if the app is mutating the latitude or longitude at all, in rate workaround cases.
I would be looking in the logs to make sure it is erroneous-from-the-system values (and not a bug in the app somehow) which is my strong suspicion. You can help confirm this via the full debug logs. Go to App Configuration > Debugging and choose the export option. You can then either: look in the logs for the word “fuzz” or send them via this Dropbox file request and I can take a look too.
This will be an interesting one to work around if Apple doesn’t fix it. A longitude of 0 is totally valid, so it will have to be based on historical data. I do not look forward to that!
