The Moon collision performance test ran quite a bit different on my PC, none of the objects got deleted and I did see the water glitch(?) (Some of the objects appeared to be large masses of water from what I noticed) Went ahead and sent the log as well. Can't believe it's been 14 years since this sandbox dropped, still having fun with it to this day.
some of those physics options were already in the game, like inverted gravity, and that weird spherical gravity thingy... (as well as the interaction physics tab)
If some of the edjected planet 9 type still are around in the solarsystem then one or two are on comet like huge orbits om 100 000 year orbits or more and at on poont comes back to the AU distance where it were formed
