I followed your directions here, James, a while ago. And as shown in my screenshot here, the referenced instance json doesn’t exist in the documents folder.
I’ll try to get more worlds and universes generated over the course of the day and I’ll try to keep track of how many bomb out or give errors vs. how many successes I have.
Also the cave issue in the first link of this post is still happening for me. I’ve tried multiple reinstalls but the default tier 3 cave node continues to give me problems.
