I am starting to see a pattern....It seems escorts first run in, with Active sonar pinging away, attack vigorously, then they just listen.

Then after 30-45 minutes or so, they lose contact, do not try to regain contact by using Active sonar, and leave....
I usually dive to 180m. Never hear pinging again. Scenario is in summer 1943
Is there a way to edit the sim. cfg or sensors. cfg. to alter the way escorts search? Kinda unrealistic.....
I have RuB 1.45, SH3 Commander 2.5 and various sound mods.
