Pathing idiocy during MSR

[srmalloy]

The 'troughs' on the top of the Rikti mothership have low domed 'lights' that would have a surface step running through them, except that there is a semicircular cutout in the step to pass around the light. During an MSR, the Rikti on the hull of the mothership are too stupid to jump, and can hang up on these cutouts, unable to figure out how to jump up onto the higher side to continue following a taunter:

If there is an easy solution to the problem, please update the movement logic for the Rikti in an MSR so that they'll at least try to jump over an obstacle the way other mobs will; it's annoying to get taunted mobs stripped away from you because they're too stupid to jump over a knee-high obstacle.
