TDW,
Please remember about two my requests, which can have influence to current AI abilities and tactics:
These requests are close to "real life":
1. Active sonar range:
It should be correct for value:
Max Bearing = 60
2. Less durability of conning tower
The conning tower has to high durability for other uboat rooms.
This is small mod which helps you find the correct way:

[conning tower has 10x less durability]
[other uboat's rooms have 50% of stock durability]
