At times when destructing built structure pieces with the building command it does not refund the resources.
Unless there is a hidden mechanic I don't know about like a grace period before you get no resource refund, the game at times just eats the resources.
I honestly have no clue on what the cause of this might be, maybe lag as for some reason in the morning my connection seems to be rather bad to the server... but you would think with lag it would just drop the resources with a delay, not never...
