I put a sigil stone in a display case and they don't quite fit. Yeah, the display case shuts but it either "burns" a hole in it or it gets pinballed around the display case abit.
You can hear the sigil stone right through the house...it gets abit annoying.
Anyway, when I came back I found the sigil stone on the floor...it had somehow pushed itself out of the display case.
Oh yeah, here's something that's annoying in the Skingrad house. Go up the flight of stairs and right infront of you is a huge set of shelves...if you look its actually split into two. Well I'm talking about the right-hand one...right infront of the stairs. Go to the far left of that shelf and attempt to place something onto each shelf. There's one shelf where stuff just falls straight through. Yeah, I duped some Varla stones to make a pretty display and everytime I come home there's one on the floor because even if you get it balanced on the shelf it will eventually fall through.
