I wanted to start my first post by saying that I love this mod

Playing it now on my new computer (with XP x64) and it works wonderfully.
But the reason for my posting/making an account is I wanted to report something that happened in one of my games recently to see if it was a bug or actually if it was supposed to happen. I was playing just regular GWX 2.1, no additional mods, and I wandered into a British port to take some easy kills before the war officially started. As I entered (after I sank two merchants in the ocean without being detected) a destroyer spotted me and began to pursue me. I managed to dodge the first barrage of depth charges and was able to position my sub just right to launch a torpedo at the destroyer's broad side. I watched with glee as I saw the destroyer burst into flames but only then did I realize it wasn't from my torpedo

My torpedo hit shortly after and before I knew it the entire harbor erupted into a huge conflict. There was a British Trawler and a British PT Boat in the harbor firing into the docks at a British Destroyer. A lot of the buildings engulfed into flames and eventually the destroyer sank the trawler and PT boat, but the harbor was in ruins.
I was wondering--was that supposed to happen? Did I some how cause the British ships in that harbor to mistake one another for the enemy/did a British ship accidentally hit that destroyer I sunk while trying to hit me causing the chaos?
Either way, it was pretty insane and awesome :p Oddly though, after I left the harbor to return to base I was getting fired on by Dutch and Norwegian ships, still before the war had begun (and there was no way they could know I was the cause of that habor mess).
I've never seen anything like it but it sure kicked me hard (in a good way xD) when I realized what happened.
Thanks again for making such an impressive mod!
