Icebergs don't make sense. Before, I shot it, got a roll of 20, and it was 9% loosened.(first shot). Second shot was 18 and it sank. This time, I got a roll of 15, it was 25% loosened, then I got 15 again and it sank. Can you please change the iceberg mechanic? The game is also sometimes EXTREMELY laggy, you can watch the video. I only had 100 cargos. maybe you can make a "Low animation mode" or something similar.
