People keep randomly disconnecting from IRC, and it says it's from a dropbear thing.
The bad news is, if the problem turns out to be something engine-based then you'll be waiting until v17 is released before the RTB beta can go out.
But on the flip-side, the good news is that I might be able to get chat rooms integrated into the initial beta in the meantime. It's not all bad news.
Ephi people found the RTB2 cached archive on google.
