Stupid lone ship AI!
 

It's seems that lone merchants only zig-zag if they become aware of the presence of an enemy ship by visual means.

So, I put two T1s at long range (surface dusk heavy seas) into a merchant. Being that it was unable to spot me, it continued on a straight course despite having taken two hits. In other words, getting hit by a torpedo is not sufficient indication that there is a threat observing you. That's funny! :)

Just another reassuring reminder that you're at war with mindless, scripted code, not fellow human beings.;)

It's like the premature explosions of torpedoes. Merchies and escorts don't pay attention to them. :roll: A definite hit to one's ego. :rotfl: :rotfl: :rotfl:

Well, yet another case of SH1 ahead of SHx. In SH1 as soon as a dud blows, you hear the Japanese escorts go active.
