Unfortunately we'll lose a lot of good bug reports by doing this, but the sheer volume of open issues (50,000+) makes it impractical for us to manually sort through everything.\n\nBug reports made through the KA site now go into another system (Jira), so it's likely that we already know about it there. But if you're still experiencing a problem, please report it again!\n"}}
