Thanks to WE and some rainy days I made some progress at the crazy sized crater project (1k diameter;) … the future surface Public Mine :
This could also be done by tech quarries + laser / manual mining , but i rather want to finish it in the lifetime of the server^^
I will try to build a railway … when the carts mod is bug free . And / or a TP pad network , where one pad leads directly above to the next pad in the line … (with cobwebs above to stay a while) … This will allow to load the whole area automatically … even with minimized MT (afk mode 
.
Thanks to Milan, now we can see the crater on livemap
