Reentry capsule There seems to be a big problem here, many reentry capsule don't have the correct drag. They maintain high speeds even close to the surface and continue to accelerate.

I had the same problem. The problem seemed to go away temporarily after I restarted the game a few times.

I've had the same problem too.

This is a puzzling error. However, it seems to have little impact on me personally. When I need to perform interstellar transfers, I always accelerate to the speed just enough to escape from the planet first, and then perform orbital maneuvers to reach other planets. I understand that this approach is not very common in the real world, but it should basically eliminate the impact of this error.

Generally speaking, it is believed that gravitational assist only applies to objects orbiting other objects. However, this limitation is actually due to the choice of reference frame. For example, in the solar system, we do not use the Sun for gravitational assist because if we consider two points on the same orbit around the Sun at the same distance from the Sun's center of mass, their relative velocity to the Sun does not increase, and thus there is no change in energy. But when we use a planet for gravitational assist, we change the direction of the spacecraft's velocity relative to that planet, without changing its magnitude relative to that planet. Meanwhile, because the planet is in motion relative to the Sun, we change the magnitude of the spacecraft's velocity relative to the Sun, resulting in a change in energy. Of course, the above energy changes are all relative.The content above may seem a bit confusing and strange, but what I want to convey is that rather than saying that gravitational assist only applies to black holes orbiting other objects, it is more accurate to say that whether gravitational assist works depends on the mass of the black hole relative to the mass of other stars in the game and whether there are other predetermined massive sources of gravity. (Since the game involves multiple star systems, a predetermined massive source of gravity is possible. Otherwise, there would be a black hole in the middle of the galaxy or the complex multi-body motion of multiple star systems, but this would require the introduction of interstellar multi-body gravity, which the developers probably do not intend to do.)Finally, it's possible to introduce a supermassive black hole at the center of the galaxy (a rotating Kerr black hole or a rotating charged Kerr-Newman black hole), and we might be able to obtain energy through the Penrose process (although the game probably won't allow us to do so). We could also introduce a black hole orbiting the center of the galaxy (a stellar mass black hole), or a black hole in a binary star system (which would involve multi-body gravity and orbiting the center of the galaxy). There may also be a small black hole within a star system (with a mass several to tens of times that of the Earth, and no one knows how it formed, which is a mystery). I'm not entirely sure, but I believe the Penrose process is unrelated to gravitational assist. Gravitational assist is somewhat like a perfectly elastic collision process (although obviously not entirely), where energy can be transferred without any energy loss.
