Sorry for double post, i just found the time to test naval combat and i think i need a new post for what i have to say.
So:
1) Keys are correct, it's just the commands that show wrong (arrow up is starboard for example)
2) When i am starting the battle, one or two of my soldiers are always stuck behind and they don't move with the ship. Instead, they are floating on the ocean like Jesus. http://imageshack.us/f/64/mb6q.jpg/ (One of my companions is the one behind)
3) When we come close to board, the enemy ship goes back and forth - back and forth at TREMENDOUS speed, so fast that the soldiers on it can't follow it, so it looks something like this: http://imageshack.us/f/339/mb7o.jpg/
4) After the two ships are united so the board can begin, my character always gets thrown off the boat (again at light speed) and gets drowned in the sea...: http://imageshack.us/f/844/mb10d.jpg/ (the same thing happens to many enemies, they are thrown off their boat and die in the sea.)
Edit: 5) Every 5-10 secs it says: battle won your enemies lie slaughtered etc etc. It appears in the screenshots. (minor bug, i just thought i 'd post it)
Fire arrows do not seem to do something for me, i shot all 40 of them and the ship didn't burn. I don't know if i am doing something wrong.
Any ideas? Maybe i should post all this to bug thread?
