I may be having a similar problem (with version 1.2, downloaded/installed today); whenever the shrine raises up into the air, I drop through the floor and remain standing at the top of the ziggurat.  When it comes back down, I come back up through the floor and can walk back out.  I'm kinda assuming you want to be up there to use the scope to see something in the distance...otherwise I can't find a "gameplay" use for it (as opposed to its primary use for sightseeing).
