no search results

I've been using DC++ for the better part of a year and now I'm having this issue where, after the program is open for some time (~20-30 minutes), I get no results when I attempt to search for something in a hub.

Some things to consider:
Yes, I'm in active mode with port forwarding set up. This function has worked fine for me for many months.
I'm running windows 10 with the latest updates
I'm still actively uploading files. I can watch people download from me.

The only thing that fixes this problem is shutting down DC++ then restarting it. Reconnecting to the hub alone does not work.

I've hunted around trying to find solutions to this problem with no success. Any help would be appreciated.
