Hi Mr TDW

I have tested your
IRAI.0.29
AI still does not solve the problem, see screenshot,Destroyer still can't found the submarine , 5 minutes later, DD is still not found the submarine。At that time the submarine is underwater 40M. Speed of 4 knots。
Original SH5 AI will soon find submarines, you want to AI become weak? Or want to change the hardware?At least your IRAI's AI weaker .
