NC: Strange Happenings

[Skyld]

I was not entirely sure where to post this, so I thought here would be most appropriate.

I have noticed a strange phenomenon, where while people are using an NC on Rudora, it can randomly disconnect when they try and use it.

NC disconnected: GrowlZ1010
New NC: GrowlZ1010

GrowlZ is on Rudora at the time of this post. He tries to use NC, and poof! It disconnects. Moments later, it reconnects. I don't suppose this is meant to happen?
