I got a temporary idea for you.
Make separate waypoints, somewhere at bottom of cavebot
that one waypoint is under hole and next waypoint is up + and GoToLabel that directs you to waypoint somewhere in middle of your Route/loop/exp label. (next to that hole, so bot can keep going)
This way when it falls into, it will find a waypoint back after few seconds. (unless it starts attacking mobs in the hole)
