Tower of Magic - Can't fly over the gap, but characters can jump over the gap

Version: 0.4.14 b

While in the tower of magic I had my rouge with fly, however the gap between the final door and the rune puzzle could not be flown over (it would continue to report that path could not be found). I just had to wait for the fly potion to wear off (ritually cast a spell) and then I could get him to come over.

Also a secondary bug which others have pointed out is that you cannot fly over to the chest in the wall (near the spider incident).
