In the tutorial, shortly after getting to space belts and working on milestone 4, a hole would appear over a platform when zooming in from the space view. The first attached picture shows the view just before the problem occurs. Zooming in just a little more results in the second image, a little more creates the third and fourth. The log of that session is also attached. Then I tried pressing the 'h' key, which took me back to the vortex, but when I got back to the platform I could not recreate the problem. I exited the game, then restarted it, but I still could not recreate it.
I tried to export the savegame, but when I clicked the button it throbbed, but didn't seem to do anything. I hit the show folder button and found the autosaved savegames, and attached to this report one that I think will show the problem, but I can't test it because the import button also just throbs but doesn't appear to do anything.
This was on a Macbook Pro with M5 silicon. It occured when the Simulation Threads setting was on Auto, and continued when I set it to Disabled. The Parallel Rendering setting was already switched off.
Let me know if I can provide any additional information.
