Yep, sounds like a good thing to mention. I assume that the NPR is using the same name theme that you are, and the duplication occurred when importing the name into your namespace Normally each race has its own name for each system, so this isn't usually a problem. There's a good chance the same bug will show up in other situations where intel about a previously-unknown system is given to another race. I'm a little surprised Steve hasn't run into it yet in his games....

PS - For Narmio - I'm 99% certain that new systems are not generated as a part of espionage. Instead, this is almost certainly a system that the NPR had previously explored.
Yes, each race CAN have it's own name for a system (it's in the "RaceSysSurvey" table), but the system has it's own name (called FixedName, no less), too (as best I can tell, the only time the name in the Survey record is ever different is a) your home system is named for your race, and b) the human player manually changes it - the NPRs go with the "real" name) - that's in the System table. The records in the System table (which is not race specific) are both "Gliese 505". Actually, I checked, and there's also a duplicate Gliese 615, as well (and I haven't found either of those yet).
I'm 100% certain systems aren't generated with espionage - you can only gain knowledge of a system the other race knows of.
And no bug is too small - I noticed someone reported that one of the "Gliese" systems was spelt "Gleise".
Looking through the database, there are several systems with "Gleise" in the name and a LOT of systems with "Gliese" in the name... it looks to me like his name generation code uses a look up table of some kind, and "Gliese" and "Gleise" are both in it... but there doesn't seem to be such a table in the database. That's really odd, since he's used database tables to hold lots of other, smaller things... strange. Can't find any supporting structure for "realistic" system generation versus random, either (one of those starting game options).
