Really enjoying FOTRSU so far except for one thing. Playing in 1941 right now and one thing I keep encountering is the insane Japanese escorts. They don't have active sonar because they're not pinging me and every time I try to engage a task force, the destroyers somehow know I'm in the area even though it's the middle of the night and I've positioned myself half an hour in front of the of the task force. So well before they come towards my pre planned attack position, they're already starting their stupid zig zags. They always seem to know where I am no matter what. It's made engaging convoys pretty much folly. I've noticed that they always seem to spot my periscope easily at night as well. Pretty much these destroyers are the only source of frustration I've been running into. Because it's like the have the passive sonar suites of warships even more advanced than the ones roaming our oceans today.......................
