/edit -- I spoke to soon, so ignore the below. I wasn't paying close enough attention and didn't realize the rest required me to go ack and activate the primary and secondary arrays again. Having done that, green arrows are back, and I'm moving forward! Reset button was the answer.
I received a response this morning, but it unfortunately was not helpful. Proposed solution was to use the "reset" button for the mission from the logs menu (done in a safe area, such as a cantina). I did that, but it did not resolve anything; the green jump arrows are still missing.
They unfortunately closed the ticket without giving me a chance to verify the solution, so I opened a new ticket. Stay tuned....
