Lost my gold smelter

I'm here about a small problem with one building that I built yesterday but does not show on the map
and of course is not there.
This is quite annoying as it costs a lot of resources.

Has anyone had the same problem (with any other building?)

It would be interesting to have access to some history of your account to check that kind of things
because now I'm currently not able to use my building and I don't have the resources required by the construction anymore,
but still wondering if I didn't build it in my dreams.

Thx in advance for reading/answering my question.
