all of a sudden, the buy side

I've noticed that for a long time NBS has had a lot more sellers than buyers. With the drop of yesterday however, the sellers have remained but there are suddenly over four times as many sellers as buyers.

Why this has happened I have no idea, has this stock gotten cheap even by NBS standards? Does someone know something we don't? Is this some kind of computer error?

Of course, the largest buyer is at one cent, so it's got a lot further to fall before that gets taken up.
