If a Vulture droid bumps on the 90 degree rotation from grappling struts (because nubs), what happens? I'm assuming it fails to rotate. Does it:

1) Still count as at range 0 (assuming it was beforehand)

2) Get to perform an action

Part of what's confusing about this is that grappling struts use "skip perform maneuver step" in their wording since they have to override the dial, which makes this more complicated than the U-wing case...

After reading the card, and RR for activation and overlap, my opinion on this is:

ACTIVATION

1- Reveal dial.

(Not 2 straight) Struts activate

Skip (2- Execute maneuver), and then, remove 1 stress token.

Try to turn 90º. Nubs bump because your side was touching, you cannot rotate and are back to your R0 position.(you didn't really move from the original)

3- Perform Actions. You haven't overlapped executing a maneuver which is the condition to Skip this step. (Same that happens with Advanced ailerons)

Imho this is simpler than the U-wing scenario:

1) Yes, still R0

2) Yes, perform action.
