I See, So if i were to go into the database and change "Chance" to 1 on every vehicle they'll all spawn?
I'll also reextract the dayz_code and take a look to double check whether or not they're empty.

I will start a new thread for Vilayer Servers as I have made some really good progress today installing stuff with their Add-on manager and I don't want to highjack this thread too much.
