OK, I have v1.01 so that must be the problem. Maybe the orange flower is also a left-over? Thanks for the info... I'll just ignore them.

And I did read the hints, guides, detailed spoilers and everything I could find on here and the internet, and nothing specifically addressed the orange flower on the north side nor the conversion of the building AFTER the school had been founded. I only have puzzles 13, 14, & 16 to complete and from what I've read, none of those involve the orange flower or school building.
