I have not been able to consistently reproduce it. The only data I can provide is that it sometimes happens, and only seems to happen if I place a ghost without holding shift. I have only been able to get it to happen three times in total, and that is after several minutes of placing ghosts. I'll update this post if I find out anything more.
I have included the save file below. I planned to attach a report, but in my testing to see if it still happens after I disabled my mods, the report was lost. If I manage to reproduce this issue again I'll attach a report.
As you can see, the invisible ghost is on the rail below the player once you spawn in. I built a station above the player for trying to reproduce the bug.
Good luck!
