When I forced an update, I got this: "Message from server: The project has changed its security key. Please remove and add this project."
Yes, I could do this through BAM (remove from all hosts, wait until they all sync with BAM and remove the project, then add it again", but shouldn't BAM do this automatically, using the same process it does when the project URL changes?
Just detach from all hosts in "My Projects" page, then go to application and click 'Tools' 'Synchronize with Boincstats'. Wait for sync, then press 'Finish'. Go back to 'My Projects' page and 'Attach all hosts now', then resync in application.
