Currently, like in many games, a ship stops blocking the movement of other ships once its hitpoints are 0. However, visually the ship does not disappear and we see it slowly sinking. As it is sinking, another ship can immediately move to its position where we see the two ships somehow merged together and this may look awkward sometimes. I have a suggestion: does it make sense to make a destroyed and sinking ship keep block other ships' movement until the sinking animation is over?
