Me again, with the problem with naming stars. I think I got it now, what is the problem. Maybe. Silly as it sounds, if the name of the system, which shows on the main screen as you fly around, starts with a [b]greek letter [/b]or a [b]number[/b], you cannot rename it to something else. If it doesn't, you can.
Please observe screenshot below. I have named upsilon pegasi to its new official name. However, as you can see, the star system name still stubbornly shows U pegasi. If you fly close, the star name is changed next to the star, and you can see on the top left the star name is changed, but the system label still says U pegasi. http://imgbox.com/jLzwxRE7
Now, please observe the star Sadalmelik on the first screenshot, 10 o´clock from UPS peg. As you can see in the second screenshot below, I can name that whatever I like, and the label does change. I can also rename the HIP star six o clock from UPS peg as well.http://imgbox.com/ohO667ta
Something in the way the greek letters or flamsteed numbers are coded bugs out renaming them. Of course, this is the lowest of priorities to fix, if the designer even wishes to.
