Beta 3: Castle Basano

[gdwright]

There seems to be a problem at the bottom of the ladder in room 16494, when first stepping off the ladder there is a recess in the floor, jumping out of this recess and then walking over the same space the floor is solid again, also climbing up and back down the ladder, quickly, the floor is again solid. I also entered this room somehow without a gold key and was not able to proceed further or go back had to abort the game.
