I believe Preston was pointing out that existing maps, that have one of 
hp/sp set to zero, will not have a hp/sp field (because object_diff() 
will remove them), but will change to -1 after the change.

I suspect there are few exits where one of the coordinates to go zero, 
but it would be good to do a search and fix them up in case.
