Cannot Find a Iron Mine After Destroying one

[Tha_H0und]

I found Iron, but it took long to build. I destroyed the building.
Whe i sent my explorer to find iron. It does not find anything.
And i Cannot build an Iron Mine on the place where I initially found it.
I am Level 18

Just send your "geogolist"(not explorer) again... Sometimes he fails, but not always...:)
