So basically, by using Spinish i can jump above my 15k cottage and fall through the roof into the rooms. However, if i also use levatation, i can prolong the jump, so that I reach the end of the house, where instead of simply falling down to the room, i ALSO go 'beneath' the floor and walk on the dirt. Which is easily fixed by simply jumping.
As i said, low priority, nothing game breaking, just thought you might want to know =)
