ok so i had a tone of problems for exporting my map because of no export foled in my update from .05 to .09 and i finally found the answer:
Just create an export folder yourself
And register it to the game.
To do so, go to the FH main folder and open resources.cfg in notepad. Look for 'FileSystem=media/terrains'. Make a new row below it and paste into it:
FileSystem=exports
Save, close
then go to the main FH folder and create a new file "exports"
this works a treat, let me know if this helps people
