Nanaki, if I understand correctly, GetRandomPortalIndexes is to set a destination portal for a convoy/fleet? So in a system with only 1 portal, the destination portal = start portal, right?

I think the problem is when the fleet spawns it also runs through the "are we at the destination portal yet?" check, so it despawns immediately. We need a way of telling the fleet to NOT check for destination until it's reached at least 1 waypoint.
