Placing resources under cliffs removes that cliff

[Natha]

When I place a resource entity (map editor or via script) on a position that collides with a cliff, this cliff is destroyed, even if both prototypes have different collision masks. Is this intended? If yes, there should be a prototype property that disables this behaviour.

The docs say "must be positive" but it can actually be set to 0. I've made a note to get them fixed.
