Just bought my first ever lair in acul, on opening up planning saw that half the top floor was unused.
I tried to fit a T1 smelter in the unused space but unable to do so, got error message there is no connection point for T1 smelter, there were connection points and the space behind was big enough, T1 smelter only needs 2 blocks.
Maybe I'm doing something wrong but cannot decide what that is.
Are there any specific conditions for building this item like orientation, which floor, or where on a floor can be built.
Any help at all would be appreciated.
