Titan is an intended part of the demo.
Interesting about methane being mentioned on Mars... That might be a bug. Can you be more specific about where it was mentioned?

methane is part of the atmosphere data for the terraforming page on mars, and I was going crazy over it for a bit thinking I missed something before figuring out it was inconsequential to the process there. cool to know titan is part of the demo though, this game is great and I've been watching the recent updates closely (even if I slow play this game way too much trying to avoid risks, almost a month in)
