scouting issues

have had some scouts working for nearly 2 years roaming an region without turning up a single search result. I began hunting for minimum 4 star potential OR ability and max age 21, from scouts with at least CA/PA 17 attributes, but even reducing the search parameters to simply 3 stars returned no results. Any similar problems, or is it just some setting I've messed up? cheers for any help

It does depend on the region and database size, try assigning the scout to a different region,
