Tested mission:
Historical mission / The fate of U-110
Installed mods:
IRAI.0.29 (complete) + FX_Update.0.5 + Environmental.4.301
All images are captured with AI sub: Lemp's U-110:
1. Lemp is run with full speed. DDs are detect him (DD changes course) but no update course with current Lemp's position.
1a. Lemp have almost perfect position to shoot. He doesn't shot.
2. Lemp is surfacing (why?), but after first hits he goes into deep. DD should know his real position and probably course...
3. But they looking for him at his first position when he was detected previously!
It looks that enemy sub is detected at point XY, and all escort ships are looking for him near XY point, with ignoring / no reaction with other (or this same) contact.
