strange export message

I was exporting a battle arena, and I got a funny export message:
I didn't even have and object named that
and
but I did have 4 starting points.
also, is there a way to decide which way the karts face when they start?
object lava.001 has property type ahead which is not supported
I didn't even have and object named that
and
you must have at least 4 starting points
but I did have 4 starting points.
also, is there a way to decide which way the karts face when they start?
