found another Bug

had explored and found a gold Node in the south of the map. placed a mine on it but due to lack of resources the mine did not start to build. Changed my mind and deleted the Mine before it had started to build but the node had disappeared so I was unable to rebuild on it. I am currently exploring to see if it repapers

I have attached a picture clearly showing a potential mine but no node symbol I am also unable to lay down a new mine. I know there is supposed to be three nodes here the third is already exhausted and the mine has been deleted.
