Yay !
The way saved favorites/viewed listings work is by storing the MLS number, property type, and other info in the database whenever a lead views or favorites a property. Then when you view a lead's listings the property details are fetched from the data feed, according to that stored info.

The fetching part was failing because some saved listings had their property type set to Commercial Sales instead of Commercial Sale - I guess that's how it was named in the code previously. Anyways, I just hacked it to transform the old name to the current one before loading the listing details.

I hope that makes sense .
