Jump jets are not nimble maneuvering thrusters; the intent is that a ’Mech can only travel to their target hex via the shortest path (i.e. the fewest number of hexes required to get there). If more than one such path exists, the player chooses which of these paths their ’Mech takes. If all such paths are illegal (for example, if there is only one path, and one of the hexes in the path has a level too high for the ’Mech to enter via jumping), then the ’Mech cannot jump to the destination hex at all. As such, the path marked with yellow dice is not eligible.
This has been clarified in the BattleMech Manual, and will be addressed in future TW errata.
