Nogoon Chono: Well, my settlement marker is basically hovering in the air, and the settlement itself is nowhere to be found too. I hope they'll fix that soon.
Did you update to the latest release? One of the patch notes that Black Iris was kind enough to post included a line "Fixed an issue that could cause some settlements to fail to appear during building generation." The build number appears in the low right corner as the game loads and is 126771.
You also didn't mention if the problem is persistent after closing and restarting the game. Sometimes temporary glitches occur when loading and exiting and restarting clears this.
If the problem continues after updating then you should file a support ticket to Hello Games. They do not participate in this forum (last time was 2016 or 2017) and you will only receive an automated acknowledgement after submitting the ticket.
Another option would be to just create a new settlement in another system.
