Usually the Osprey cannon kills the prey but this time, it left the enemy stuck in a neutral state.
There was a message about the enemy ship that was activating it's FTL drive.
Then about 3 seconds later, the enemy ship was attacked by my beam and left it at 1hp, neutral state. He's not activating it's FTL drive to go away and I was not given any loot.

All I can do is jump to another star system.

Any chance you could have accidently hit a weapon hotkey and accepted a surrender that popped up without you realizing it? It's a common problem.
