Glad to hear it. If that is how it's supposed to work, I'm totally fine with it, and the rationale makes sense.
In fact, I did just now successfully lock and track a target long enough to screw up a firing solution. On the plus side, I hit a ship at the far opposite end of the convoy! A tanker, with one magnetic pistol at god knows what range. Poor guy just walked into it.
The destroyers had no idea where I was... until I got greedy. The Irish Sea isn't too deep.
