What happens if you're on terrain, and are pushed to a location you cannot stand on?

[Ravnak]

If I'm stood on the roof of, say, the official NYC building, and a short push puts me on a part of the building I can't stand. (Either a none-flat part of the roof, like the skylight,  or overhanging the edge).

Do I just stop short? (Or not move at all if theres no legal place to be pushed to).

[Negoldar]

The pushed character will revert back to the last position it could stand on. Note that for a throw collisions that would have happened if it could end where it stopped will still happen even though the character had to move back.
