Invisible base computer solution [Bug]
1.) Backup your save files!!! It is under %AppData%\HelloGames\NMS
2.) Download save editor https://github.com/goatfungus/NMSSaveEditor
3.) Unzip it and run NMSSaveEditor.bat . Under Game slot, choose the save file where is the buged base.
4.) When it is loaded, go to Edit / Edit Raw Json. Open "PlaterStateData" and find folder "PresistentPlayerBases". Here are all your bases marked with numbers.
5.) Find the base, with invisible computer. Just click on the folder and scroll down in the code. You will find the base name there.

6.) Bases without bug will start with "ObjectID":"^BASE_FLAG",

Corrupted bases don't have "ObjectID":"^BASE_FLAG", code line. It will start with an object from your base.
Now copy the first "object code" in the file as you see it here.

(select with mouse and ctrl+C ) and after "Objects":[ hit Enter to make a new line and paste the code there (ctrl+V)
The duplicated code will look like this:

7.) Click anywhere on any other folder and save the json file. If you not made any mistakes it not will show any errors in the lines.
8.) Exit the json editor. In the main editor choose File / Save file.
9.) Go to the base, and find the base computer. It will have a different position now (maybe upside down, my was underground on a bottom of a battery). But finally you restored your base computer, you can delete it or move to different position.
