haven't attempted placing one of these yet myself, what with all the trouble there's been with them..... only advice I can give is the very basic stuff, which you probably have already tried
not knowing what part of the item is actually the 'placer' is the tough part, so maybe start with like the second row of tiles of the west edge of the space and target each tile in turn, then move to third row, fourth row and so on
seems to me it should go down somewhere as I recall that EA said it only needs an 8x8 space to sit down
