Hi there, thanks for playing!
Sometimes materials will be under the terrain, for you to collect later after waiting or receiving a significant upgrade. I’ve made a few changes that might help. These are now harder to hear in scan results, more muffled sounding overall, and have a transparency effect applied. The upgrade is coming soon.
Also thanks for providing me your location! Your report reminded me that the Status screen is missing some very important debugging details: the world seed and mission time. These have been added as well.
