New IP breaks hobbit

So... While I was on vacation for a week, someone changed the IP address of the machine that I run Hobbit on, and of course everyone else is now out sick, so I have no idea why. I came back to Hobbit rather pissed off. I changed its IP in bb-hosts and hobbitserver.cfg but after I restarted it, it loads all of the alerts purple. I'm running RC5 on a Gentoo machine with a 2.6 kernel, and didn't see this as a documented bug. While I noticed that RC6 is out, I'm playing catch up from vacation and won't have time to upgrade just yet. Just thought I'd ask if I was missing something easy... Do I have to change the IP elsewhere? Thanks :)
