I can't really remember this happening before, but F@H has been trying for more than 12 hours now to download a new core (to me). I keep getting: Error: HTTP GET returned error code 404 on every attempt to download the core. I've already tried kill the "fah5" process and starting it again, which did start the download attempts anew, but still no joy. Seems odd to be given a WU when the corresponding core seems to be unavailable. Any suggestions on how to proceed?
