gathering and mining spots at nodes

Hello,

Some gathering and mining spots are missing at nodes.


The notes already activated / connected to look whether the then come and after each server restart I also check whether it is now there.
With my friend are there. So there are the ones here as well.
Or do I have to do something specific to get that?
My workers need employment :-D ask for help.

It is about the spots in the Mediah -> IronMine.

 

Does anyone know why the spots are not there? Or maybe I forgot something or did something wrong?

 

There is nothing wrong with it
