Both object are shown for me. Thought Nishimura has rendering artifacts.

cmodfix abnormally terminates with Nishimura

The same for Dinkinesh

It was unrelated issue.

Regarding Nishimura's artifacts - they are caused by presence of alpha channel in the base texture. Celestia in such cases enables blending. I recommend removing it, for example converting to jpeg.
