What happened

A router source set key and its rowKey is a function that reads zero or several row properties, so the router cannot work out which single property to prefix. Ids are left un-namespaced, and rows from different feeds that share an id replace one another.

The fix

Use a property-name rowKey, or make each feed's ids distinct already.
