Beam volley gone after reload

The beam volley is not available after reloading a campaign save game. After restart the game the beam volley is available for the same save game.

I'm playing in German, but happens in English as well.

after restart:

I can provide the save game if necessary. 

Update:

The button is still there and I can execute it, it is just invisible
