If you see the picture above, the white lines doesn’t match with the actual model from the house. There’s 6 stakes in the edges of the house and 2 in the middle. The one in the bottom right is not alligned with the model shown in white.
Because of this there’s a hole between the house and the palisade wall but you can’t see it.
This is clearly a bug that can make you lose games because you think you are fully walled while you are not, and since you can’t see it, the only way is to test with a palisade wall, which you can’t always do because there’s a lot of things to micro at the same time, specially in empire wars.
I don’t have the possibility to add all the detailed information bug posts are suppossed to require but i think that this is pretty straight forward and buildings should be more clear over the grid.
