Hey, if you could grab a screenshot of this issue, I could look into it.
It's supposed to offer the ops complete units to do op fire, and a fate marker would appear on the hex they shoot at. The ops complete status is only removed (and the points only get spent) when the op fire actually happens, so it has to be confirmed AND the operation of the enemy unit must get to a point where the op fire can happen (if they get disrupted at a previous step, the op fire is skipped)
