Vanilla bot is not taking flight paths

When I'm on a mount and go to a flight path the bot talks to the flight path npc and I see it click where it wants to go while still mounted. But because its mounted, the bot doesn't go anywhere. It will sometimes dismount after already clicking the destination to fly to, but instead of clicking the flight again while dismounted, it just mounts up again and starts walking to the destination or to next flight path along the way. Any ideas how to fix this?
