I found what I had missed earlier. I loaded into the editor as a rifleman [AT] and it only happens if you are crouched, and in first person. After you have shot the NLAW immediately hit escape, and switch to Splendid. You should see it happen from there. I did notice it's not as frequent. but I have attached a screenshot I hope that helps.

Absolutely. I will be on later tonight, and will provide some screenshots, and more detailed steps to reproduce this issue.
