Early in my game, I had to quit for dinner, and reload later on via auto-save (I also tried earlier quicksaves), and all of a sudden the anomalies became invisible. Reloads, game restarts, system restarts all did not fix it. Using what I believe are the latest drivers for my Radeon 9800XT.
I can still mouse over the anomalies if I get lucky, and was even able to grab 1 with my surveyor...but this is odd. Is there some kind of option (though I can't imagine 1 for this) for this that I might has miskeyed by accident?
I'm *not* talking about the mini-map, which has anomalies on/off options.
