/area_pos set does not work on some nodes

[SwissalpS]

I was protecting an area with pipeworks:deployers in the corners. It would not work until I replaced the deployers with some standard node and put them back after protecting area.

Areas depends on the register_on_punchnode callback, which is not run by pipeworks' on_punch callback.

If this is an issue, please blame mods that do not run this callback - though I wonder why it's not done automatically by the engine...
