Enabled the Lifeboats mod, continued an existing career and proceeded to eel a Tribal class british ship, but no life rafts, no debris. It never totally sank though, after waiting for 2 hours the bow was still sticking out of the water a bit and it would intermittentlly catch fire, but never looked like it was going to go any further down, then I had to scramble away from that point because another Tribal was coming in hot & heavy. Not sure if the lifeboat/debris mod doesn't work because of the conflict listed in my previous post, or if that stuff comes off the ships right as they are completely going under...
