I just started and ran into an issue while building my base according to the tutorial. I couldn’t build any of the starter buildings the tutorial tells me to because it was requiring materials I didn’t have (poly-sulfite sealant etc.) I asked for help in chat and someone pointed out I shouldn’t need those materials and suggested I try reopening some windows. I opened the “Buildings” window (for the first time) and then reopened the construct window and the extra required materials were gone and I was able to construct the buildings.
Thanks for the bug report! We’ll look into this!
