SCNR.META Editing Question

[DECOY]

I have been experimenting with adding additional vehicles and items to
maps by adding them into the scenario file via scnr.xml, just prior to the
rebuild. (So that I dont have to swap them for something else on the
map.)

They are not showing up on the map when I run the game, but if I open
the map with Sparkedit, they are shown as being in the location I put
them on the map??

Any help appreciated.
