I haven't looked at my own signature graphic in over a year, but I notice that it has dropped all retired projects. I know that at some point this was not the case, as Tanpaku had been retired for years yet was still in my signature graphic. Now all the oldy-moldies are gone. Is this a new mandatory "feature", or is it a setting that I can toggle somewhere. I think having buttloads of orphaned credit from old projects is a way to separate the veterans from the young whippersnappers!

Looks like a Classic "Split CPID". There are many, many topics on how to fix that here in the forums.
