Quake3 has a problem where if you have too many maps then they don't all show up in the map browser because of a memory override bug. Beast fixed this ages ago, but it didn't get applied to the ioquake3 code until today. I'm subscribed to the ioquake3 commits mailing list and I was very happy to see this today...
