I found 2 bugs.
1. When a supernova begins and I zoom out, there are lines coming from the supernova that go in all directions. They sometimes flicker.
2. Sometimes, when I select a star, it's prediction/orbit line's end follows the camera which I find kind of odd.
Also, Supernovae shouldn't collide with the camera. It's hard to zoom out when you are in a supernova.
Screenshots are attached below.
