Twitter cards not showing up for some urls

Twitter cards not showing up for some urls.
For example http://yplanapp.com/event/2112/meet-the-expert-oz-clarke/#?deal_id=2112 validates but no card appear.
The strange part about it is that tweets still have “More”, but if you click on it tweet expands but no card visible.

Other links from same host works fine ( for example http://yplanapp.com/event/2143/othello/#?deal_id=2143 )
