Planet Names missing

[Suicide Junkie]

Sounds like you've got the name display option saved with your race...

1) Click Empire Status (F11 / Crown button)
2) On the top right, click "empire options"
3) Scroll down to system display, and make sure there is a green dot beside "Show Planet Names"

Of if you are using the FQM mod, make sure you copy the systemnames.txt over to the current datadirectory. It contains more than enough systemnames.
