Just finished this excellent game. One question bugs me, though. In the post-credits scene, in the simulation onboard the ARK I saw a lot of light blue square patches here and there on the terrain textures. I also noticed two (AFAIR) instances of such patches on terrain textures on the ocean floor when moving between Tau and Phi. Is this just a glitch, or is this a hint at something bigger? A cursory Google search didn't achieve anything. Thank you!
