The missing character in the CG room requires that you keep Grey in his changed shape after the events where you train with him and he gets into trouble at the bathhouse. The events start at the Aldlyn city board if you haven't seen it yet.
Research seems to be a bit bugged and sometimes doesn't finish. I still have to figure out why.
The CG scene for the custom made girl from the christmas event is a bit delayed. I plan to release a normal update in the next few days and put that special scene into the next update.
