I was playing as the Prussians and i had a single merchant in french waters and he got attacked by a single french frigate and couldnt escape, so i just decided to start the battle and withdraw.

I set my ship off withdrawing and put it into the crew view where you see on deck...

Then i noticed it... when the crew members walk up the stairs, their legs move so fast, its hilarious, and they do the same when coming down only it looks like they're almost falling down the stairs hahahaha

Look out for it when you can, i had a good laugh for a minute or 2.
