Hi flutefish -
I've tested this puzzle just now and as far as I can tell, the clues seem to be accurate - I was able to solve it using the given clues and found no paradoxes or discrepancies. I'm posting a screenshot below to show the solution as well as the clues, together.

The confusion may be that Ivy isn't younger than the bedroom - the clues actually says that the bedroom is younger than Ivy?
