I find it weird that when I press the dive option below the periscope depth (that is 40 m below surface), my sub cracks open like a walnut. As far as I know i have no serious damage, unless you consider a broken radio (which is already repaired) serious.
Anyway it bothers me, how can i run from destroyers if my U-boat goes into oblivion when I go below 30 m depth. Anyone can help?
On a side note, great game!
