Merchant bug??
 

Im out at sea trying to complete the 200k objective, and i find a lone merchant vessel. i hit him with a torpedo, and i surface to finish him, and he starts firing the AA machine guns. he fires a little and stops. all of a sudden im getting heavy flooding heavy hull damage lots of things damaged /destroyed and 15 seconds later i die. he isnt firing a deck gun. he even stopped firing the AA. but still my boat kept taking damage for no reason.

any1 else expierience this glitch?

it just happened AGAIN exceot i didnt die this time but he left me with 53% hull integrity when i had 97%. and this 1 YET AGAIN had AA guns. how in gods name do AA shells do that to a reinforced steel hull.
