In a tour rotating about a reference frame longitudinally and crossing from a negative longitude value (as seen in the timeline) to a positive longitude value (or vice versa) causes WWT to take the long (usually opposite of desired) way around the object.
The current work around:
Goal to rotate from -150 degrees to 30 (a change of 180 total degrees)
Change final value from 30 to -330, so that the new rotation is from -150 to -330 and this will rotate the desired direction
