I wouldn't necessarily call it a bug, which is why I'm posting it here, but if you leave Myrellion after doing KaraQuest2 but before getting the probe and then get the event where you help Zaalt adn then exit your ship on Uveto the game will automatically move Shade to Uveto. This completely blocks yourself out of the reveal. Made this unfortunate mistake and thought I'd mention it so others don't make it too, if they want the reveal path. I kind of wish the Zaalt encounter was disabled until you get the probe otherwise I'd have just stayed on myrellion and got the probe. Sadness.
