As I mentioned in my other post I have now patched Nergal with the new observer code update. You can now view all objects in a sector from wherever you are. If you deploy a mining colony in a new system, you will be able to still view the other planets in the system.
I think it's working correctly, but it would help to have some testing done. So fly around, see what you can see. I'm mostly interested in the edge cases, like if you can still see the planets after your last ship leaves, that sort of thing.
If nothing serious comes up, I'll patch the other servers Friday.
