[BUG] Failed to calculate primary body between Ganymede and Ganymede

[OPdemigod]

1 - Create a new, empty simulation
2 - Add our sun
3 - Add 3000 Ganymedes in orbit around the sun (tight orbits)

The game will become very unstable and / or crash

After checking the log files I found the following error:

"Failed to calculate primary body between Ganymede and Ganymede"
