Hello,
I'm writing on behalf of a client. He's configuring a Social Stream and made a modification on the configuration by adding a filter to include only posts that are not assigned to any user.
After a couple of days he checked back on the stream and noticed that this new filter wasn't there anymore, this also happened again at a later time (he added the filter and after some time it wasn't there). He's sure he saved the stream after doing the configuration.
I tried to replicate this behavior on a stream I created myself, but the filter stays there. Do you have any idea of why that could be happen?
