First, I have yet to find any black holes without accretion disks. Even all the solitary black holes I have come upon have accretion disks and I'm not entirely sure this is intentional.

Umm, is this a glitch or is it just me?

I just noticed something. I was looking at the_nerervarine's link, and I saw that the "LoaderQeueSizeCPU" and "LoaderQeueSizeGPU" are half their values from previous incarnations of SE, in main.cfg at the bottom section. In RC 1 they are 64 an 128 respectively. In previous versions, they are 128 and 256 respectively. As a result, I was seeing incomplete loading of various planets as well as missing Solar System browser thumbnails. While I think folks with higher end machines need not to worry, setting the Qeue sizes back to 128 and 256 seems to have fixed the issue on my low end machine.

1. After you build your ship, and engage the hyper drive to go to another star SE crashes, but if that particular star has planets and one of the planets is selected SE will not crash. It seems not to crash ether if you use the hyper drive to go to other galaxy s.

I have found that the problem that I have posted here, is not resolved. I can handle this error when I use always 'RadSol'; but if I have edited an object in the editor and then export, 'SpaceEngine' always writes 'RadiusSol'. Which of course leads to an incorrect star diameter.

hanvulansia, SE requires OpenGL 3.3, and you have 3.1. Try updating your video drivers.

Okay I know it's sort of bad form, but given that the last page ended with a response from SpaceEngineer to some recent posts that didn't include mine, I worry he didn't end up seeing it and that it's been buried. So here it is again:

Alas, I too have found a bug.
Some of the moons (I have yet to find a planet that does this) have a temperature of -1 K. They cause serious lag when pulled up in the solar system chart thing (F2), never load their textures (just a black sphere), and after a few seconds will crash the game, unless the chart is closed and the system unloaded.
Here's a screenshot with an example of such a moon:

And an SE.log on the off chance that it helps: https://dl.dropboxusercontent.com/u/13276416/SpaceEngine/se.log

Hopefully this is just something wrong with my configuration settings. This didn't happen in Patch 8. The affected moons appear to mainly be titans, although this may be a coincidence.
A hypothesis: When certain moons are warmed by tidal heating, things that should be ice get converted to greenhouse gases, causing their temperatures to rise exponentially, turning even more of their interiors into greenhouse gas, until the temperature becomes infinite.
Interestingly, these moons also seem to not have proper diameter values, even though the information panel claims to define one. Zooming in on such a moon shows nothing (no moon), and then at a certain distance threshold the entire screen becomes black - there is at most a single frame in between these states.
