I found some bugs in the educational activities:
1) The .ssc files for the Helios 1 and 2 spacecraft do not have a texture defined. This makes them rather hard to see.
2) The asteroids-educational.ssc file doesn't have the correct mesh for Ida: it points to a .3ds file that doesn't exist instead of the .cmod file that does exist. (This is for Activity 4.)
Besides that, the files seem rather disorganized and the documentation is in places out of sync with reality. I've read some topics that they would be reorganized and updated so that they conform to current "how it should be done" standards. As I understand it, best practice for addon files is that absolutely nothing should ever be put in folders together with existing Celestia files, which isn't the case for the education files: several extra models and textures are placed in the base folders. (Correct me if I'm wrong about how it should be done.) Is this reorganization still going on ?
(I hope I haven't said anything stupid in my first post here.)
Edit: Same problem for Dactyl as for Ida. Kinda annoying when the accompanying document tells you to look for something and you don't see it.
And now that I think about it, there's something else: in activity 4, you're supposed to see Jupiter and Io when clicking the link at the start. But, I don't see them.
Edit 2: Saturn's moons have disappeared. While I could still select and focus on Ida and Dactyl, just not see them, I can't even do that for those poor moons.
