broken ladders

[rose]

There are several older games that have ladders that look broken and they also makes Jack fall and lose lifes. This is in MM 1 on Snow Leopard. Here is a screen shot from Jumps where I cant't pass the ladder and continue with the game. I wish I had made a note for the other mansions I had problems with.
Is there any mansion builderout ther who know how to mend the masnons broken ladders?
