I have someone who is having trouble with her saved queries. She had previously created and saved the query and run it successfully. It was a shared query with 1 other person (it has also now been shared with me so that I could help with the problem). It seems as if all of the conditions of the query have been lost. I.e. when the query is run it no longer returns the same data (should be about 51 items) - it now returns 14761 items. And when the query is edited it shows no conditions at all.

This sounds like a data loss problem of some sort. Suggestions or ideas welcome.
