.Map :: MoHAA Mapping

For some reason when i save something as a Prefab and then try to load it into a map Nothing happens..

Are there are any rules to go by for making prefabs??

I think the entire prefab has to be selected when u save it as a prefab for it to work... if that makes much sense

Till now ive been copy these to a blank map and just saving them as prefabs but ill try that thx
