Upon downloading the latest update via Stardock I have encountered this issue.
For some unknown reasons the Planets, Starbases and Galactic Resources will not appear in my galaxy. My settings are set to show them, however I only get the tactical view at all zoom levels.
It does not appear any other graphic issues are present, background, pathing, ships, influence borders and combat all work fine.
I thought it may have something to do with the size of the map, I have found that smaller maps do not have this issue as much as large maps, however Smaller maps still tend to lose the above items on occasion. Restarting the game will sometimes recover the graphics on smaller maps, however nothing seems to help the larger ones.
