Been a while since I played SH4, can't remember anything. I have version 1.4, which near as I can find is the latest patch. I'm still getting this kind of nonsense;
After evading a depth charge attack and clearing the area, I surfaced only to find I can't move on the surface. 2 diesels destroyed means I still have two undamaged and theoretically operable diesels, but whatever I set the telegraph for it just won't go. What's the point of surviving if you can't get back to base? I've had the destroyed rudder before, but first time I've seen this, half the engines gone means no moving no battery recharge? Hard to believe this bug hasn't been addressed someplace.
