Amen to number 1 in the post above - the battery life/submerged range not working correctly has frustrated me for a long time, and defied all my efforts and wasted testing time trying to make it work. Worst part is that IIRC it was actually working at some point (maybe patch 1.2 or 1.3) but got broken again and seems to have stayed that way. I know it's possible to stretch it to something that isn't completely unplayable and some mods have done so, but a fix to make it conform to historically correct parameters would be great.
And BTW - the convoy milling around issue mentioned in my previous post was not like a conscious attempt to "go dark"/quiet - the ships were still steaming (so making noise) but just doing it aimlessly at slow speed, milling around in daylight for no reason - very immersion-killing (what's the point of trying to conduct a running convoy battle when the convoy isn't running?)
