So i found a model online of the spaceX starship and for some reason half the engines on the bottom are gone after the slice on the solid view it is still there but the hole model is pushed down. I have no idea why it does this any help is appreciatet.
I have included a picture of the solid view and a layer view of it and i've also included the model itself.
