It lost 3 positions...so its not the end of the world. We all know a big difference between ranking #1 and #4 though.
I do believe that what google is doing is counting all the links from the network as 1 link...which it SHOULD do to begin with. I dont think this is really a penalty, just an effect of the changes google has made.
