Thanks for reminding me about this. I now have even more creative worlds, each one with a specific class of tech. As long as my saves stay, I'll have all the designs i was able to salvage or rebuild. I would recommend this to everyone on Xbox until the devs solve this issue. I know they're looking into it, so any info anyone could add to this would be great. Currently running 188.8.131.52 on Xbox 1s. Check out my thread, Tech designs gone on console for the current talk with the devs.
