Thanks a lot blazemonger. It did not work but I have learned a lot. I created a core and had it in my inventory and used the repair tool.
Without the core I was told "Cannot repair destroyed Element.You do not have the necessary Element to replace this one"
With the core in the inventory it said "Cannot repair destroyed Element".
Instead I took my new core and made a new setup beside the old one. I found that I could remove the materia so all I lost was the created storage containers and mining unit and a couple of windows etc. Anyway I still have 28 days before it breaks down completely so no worries 🙂
My new problem was that the resurection node also broke. I repaired it once but the next day it was bad. Solution - I bought a new one.
My only problem was that the nearest one I found was still across the planet, so it took me quite a while. Luckily I had read a tutorial so I had lots of fuel and scrap with me. Crashed something like 8 times, twice upside down... so now I have learnt to fix that and repair it as well.
Next step will probably be to learn to fly a real airplane. I guess they are expensive as well so I had better keep on mining. I have four mining units now 🙂
I will join the Discord to learn more.
After two days I was ready to quit, but now I am starting to understand something and enjoy myself. It still feels empty and lonely, but hopefully I will get to know people when I learn how to transport myself in a better way.
