I add a default galaxy in an empty universe, but it slowly breaks apart by itself. Galaxies doesn't break apart themselves, is it? So I think this is a bug.
Here is a (hidden) video of this effect. It happens the same even when changing parameters, except the one that includes dark matter (galaxies without dark mater are stable in US2
)
