Nah, works as it should actually, I'm pretty sure of that now.
Thing is I intercepted another convoy just this morning, and the escorts actually did what they did in the test mission too, i.e. got a hunch of my whereabouts and threw some DCs - but the bubble cloud then fooled them a bit again and thus presented me with a chance of creeping away! Mind that they DO find you again if you push the pedal to the metal, bang kettles, loudly sing derogatory songs about Stalin / Churchill, etc. so not too much noise is still a must (as it should be).
So yeah, looking good indeed
PS. Do I spam too much here??? I've a habit of slipping pretty easily into a ramble mode and that sometimes shows
