I saw that you could use goza's to break a soulforge to make it smaller. I've placed 16 goza's, raised them up 2 times and tried to place the forge but it will not let me .. has this been changed so you can't do it or am I doing something wrong?
you can't do that "inside" your house, because the roof block the construction. Just do it when there is no roof and all will works
Depends which floor its on - if its on bottom floor of custom house you just need to delete a 4x4 space in the floor above it.
