This is about the scoring system in multi ship games with captured ships. It might be a bug, or perhaps I just don't understand the scoring system

In the game above a ship (amphion) was captured - but the person who captured it (steveh) didn't score any points in the 'captured' column.

And then when another player (szurla) later 'striked' that ship (now controlled by his enemy steveh) he (szurla) scored no points for 'striking' amphion.

But steveh was then awarded the points for 'striking' it.

is that a bug - or if not what are the scoring rules? clarification would be nice

Thanks
