There were some other problems like that. I made a list for you, but I sadly lost it. The pack is great though, correcting those errors was definitely worth it.
I can load the core pack, but if I try to load another pack in groups of 40 or even put other textures in the game it doesn't load anything anymore. What should I do?
I didn't do orbits back then, because it was hard to do with that version of the game and I didn't really understand the physics behind it. Today I would use orbits.
