Help with my attack at Scapa Flow

[Joaoperru]

Greetings gentlemen!
I'm new to this forum, but i've been reading your interesting posts for a while now... and every time i learn something new about this really wonderful game.

So... i come out with a question myself.
Yesterdey i sneaked for my first time in Scapa Flow. I was so excited...
I've found a Fiji Class Light Cruiser, as lots of you reported. I readied my fishes and shot 4 of them at it.

And nothing... i mean... i heard the BOOMS... but no water in the air, no damage to the ship... and after a while the guy screaming "torpedo missed, sir". Everything was all right at the moment of the launch, it was an easy stationary target, and the range was perfect.

Then i tried again with 4 more. The same.
Then with the last 2 ones. the same.

I was i shallow waters so i thought my fishes hit the ground. But even trying to set the depth to 1 m didn't solve the problem.

Then a i depleted my ammo and i headed back to base, astonished...

Damn... havent read anything like this in these forums... so i'm asking you what could have been....

please, kind captains, enlighten me!
