AI Bug. IRAI o stock SH5?

[Warfox]

Hello again Captains!!!

The bug is following:

I was hunting in December 1939 near the british north Coast when two Destroyers spotted me and began running towards my sub. I ordered crash dive and maintain full engine power until 80 meters. Then we dived to 160 meters in silent running. My experience in SH3 tells me that a 1939 destroyer cannot hear a sub in silent running at 160 meters. The thing is, that ALMOST all DC's failed (except for 1 out of 10 which causes minor damage) to hunt me but the destroyers followed me for 6 hours. Then I ordered All Stop, but they keep on knowing where I was and were patrolling over me. 18 hours later a bunch of 7 Destroyers appeared and finally after 2 of sneaky combat they sunk me with DC's.

Most of the DC's fail, but they still run over my position with a scary precision. It seems they always now my exact position, although I am at 160 meters in Silent Running or at all stop.

This is a really annoying and realism killer BUG!

Anyone has the same problem??
