Provided that there was no bad interaction that could result in the owl puzzle being incompletable what's the issue here? I remember one puzzle in particular, the building it was on looked like some kind of academy. Pressure plates were on the roof and I was flying around for easy access. It's not worth saying "oh god I have to dismount, the horror!" but honestly why remove common-sense functionality from puzzles? It's a pressure plate, I have a metal horse.
