No sir. It is
not a bug. It is the limitation of the code.
Until very recently, no AI submarine can dive from the surface in SH3.
GWX Dev Team member 'Privateer' was the first to discover how to make them dive. However, once submerged other problems remain for these diving AI subs. Until these issues are fixed, there will be no diving AI subs released by the GWX dev team.
Also, when you torpedo an AI Submarine, it will usually take a long time to sink. We had to make the damage model as such because of other limitations relating to Silent Hunter III.
Again, what you describe is NOT a GWX bug.... but is a limitation of code instead.
Try to remember, that we are modifying a game that is three years old now.
If you have never played stock SH3, it will be hard for you to understand. Many many improvements have been made, but some things may prove to be impossible in the end.
It isn't so bad now. We can fix many things, but some quirks in SH3, we will have to learn to live with.
