Sub not responsive
 

I came across this frustrating bug where the sub will not move or dive at all, ahead full, back full, crash dive, return to course etc, nothing works. It simply just sits in its place. All the crew are in their right positions, especially the engine room. I tried with battle stations ON and OFF, still nothing. and I don't get "Cannot comply" either, I just get regular order confirmations as if its working normally.

Using Fall of the Rising Sun mod + 399_NoScrollNavMap + 650_LotsaDudz which are integral addons of the super mod and not 3rd party mod.

check your engine crew's fatigue level.
if you were at battle stations too long, everyone will become fatigued and the engines will not respond to your commands.

That's still true even if you turned off battle stations.

I checked and its not that sadly, all the crew were rested/low fatigue and the green bar in the engine room was near full even without battle stations. I waited about half a day for fully rested shift to take over, still nothing. It was a simple agent drop off the coast of japan so I didn't really have battle stations on any way. The bug happened when the sub reached the end of its course, near the coast.

I will replay the patrol to see if it will happen again.

I have had this happen a couple of times.
I tried all kinds of things, but it seems that if I went to "all stop" then rang up a bell it would start moving.
worth a try anyway.

I encountered a few of those "mysterious" bugs but none were patrol-ending like this one. It's a shame since the game is alot of fun.

Did you save, exit, then restart? Sometimes that will fix bugs.
