Page Event Crawler seems to be working no longer

It seems Facebook changed their page's upcoming events structure severely if my observations are representative.

Example:
https://www.facebook.com/changa.dance/events/?ref=page_internal

If you are not logged in, you only see past events now + even if you are logged in - the data is no longer delivered via html if my analysis is correct so far.

Start by examining the crawler's Facebook event-fetching path and compare its current behavior with the example page in the issue, both logged out and logged in. The work is done when upcoming event data can be retrieved despite Facebook's changed structure and the crawler continues saving event details to MySQL.
