Stiebler, thx for your reply. I am going to give you an exact account of a test patrol I did today.
I quit my carreer, disabled the sabotage and malfuntions option in commander and started a new carreer. Type IXC, 1940. First patrol started ok. Did some testing in deep waters. This time the boat kept periscope depth while silent running. After that I did an crash test dive and even this gave me no problems. At minimal speed I kept 80m depth for more than 30 minutes. A few days later(in the game) I got a contact report for a convoy. I raced my sub to intercept it about 12 hours later. Dived to 30 meters, did a soundcheck (convoy was closing). Decided to stay at periscope depth and manouvred my sub inside the convoy. Fired 6 torpedos (2hits2miss2duds) dove to 30 meters and came back to periscope depth behind the convoy. Escorts were looking in the wrong place. I resurfaced and started reloading while getting back in attack position. This time a did a surface attack, sunk a large tanker and I was discovered by a escort. I decided to to a crash dive and THAT is when I encountered the problem. The crash dive did nog stop at 80m, the boat kept dropping and could only rise at minimum of 5rpm with straight rudder. Even when I rised to 60 meters it kept dropping back. I had no damage to my sub and I was not hit by the escort. 3 times I tried to blow ballast only to rise 10 meters before going back down at a rate of 1m/3seconds. Because I had no change of evading in silent running a let my sub rest at the bottom at 138meters. I had to go to work so I saved the game a few times and will continue tonight. Do you have a clue as to what triggers this extreme sinking behaviour? Seems to be triggered by the crash dive but only during the convoy attack... not during my first test crash dive. Blowing ballast in this case does not help? If I survice the attack I am going to do some more testing. My realism settings are all checked exept for realistic repair time (becuase this is already in the patch) and external view. All advice is welcome
