Well, I've run into the same problem but I use no mods and I don't use an s-boat either. So how do I solve it?
I started a career in 1941 with a Porpoise class submarine, I was stationed in Manila. So first mission I had to deploy to Celebes Sea. Once there I was asked to engage and destroy enenmy merchants. So I did that and went to Soerabaia harbor to end the mission. Once there, I decided to resupply and destroy some more, even though I had completed all objectives. After that I went to look for enemies and all of sudden my sub didn't move anymore. Same thing: Every command was replied with: "Cannot comply!" Went to an earlier save point and after a while again the same problem, sub won't move and all they say is cannot comply.
So the bug is also there when I load an earlier save game, in other words: I should give up this carreer and start a new one? Who tells me this won't happen in a new career also? Really, REALLY annoying so please help me guys
