Whenever I compile my map the modded vehicles I put in never show up in the actual game but the vehicles that are supposed to be in the game like the ghost & warthog do show up. They do show up in sapien but not in the actual game when compiled. This is the case for all the modded vehicles i try. Any ideas?

You have to edit globals.globals and replace the six listed vehicles with the six vehicles you want to show up in the game, and make sure that when you place them in Sapien you also checkmark the gametypes that you want them to spawn in.

It is possible to have more than six vehicle types spawn in a map, but it requires some scripting. I don't think it's anything overly complicated, but I don't know much about it.

Assuming this is a multiplayer map, you are limited to six types of vehicles in the globals.globals tag. If you want more, you can script them to spawn on the hosts computer only, and the game will sync them to the clients.

How do I edit globals like that?

Go to tags\globals\globals.globals on guerilla and scroll down to the multiplayer information block (about 75% of the way down), then to vehicles, and switch one of the first six vehicles in the dropdown with the one you want to spawn in your map. If you don't do that, it will only spawn if you create it with scripting and you'll need to do some trickery to get it to sync properly.

1.) Open up "Guerilla"
2.) Click on "Tags"
3.) Click on "Globals"
4.) scroll down to "Vehicles"
5.) replace what vehicles you need with ones that are in here

* you can only have 6 vehicles in this tag "vehicles"
these vehicles need to "match" what you have in Sapien

* make sure in Sapien that you click on what "gametypes" you want that vehicles to spawn in

* if you want more you need to "script" them in...go to link below for more info on that

You can edit them with HEK's Guerrilla, or a functional equivalent. The globals folder is inside your tags folder.
