no hold fire button
 

I am playing OM first patrol i cannot tell the gun crew to hold fire when the target is sinking so wasting shells .The only way i found is to stay at the gun position and not fire or submerge
all so no cannot find charts or flag sheet for when countrys change sides.ship routes .port mines or nets :hmmm: still it is a great game hope silent hunter 5 lives up to sh3 and sh4 (with the help of all you moders out there):DL of course.:salute:
Does the sonar only show the bearing but not the sound on friendly, but bearing and sound on none friendly ships and is this the reason for no flag chart.

dont know if thats a stock bug or not. i also play O.M. (not w/ OMEGU) and what i can suggest is either saving/loading and see if that fixes it,or simply securing from battlestations,and like you said,work the deck gun manually.

hope this helps.

I don't know about the u-boat missions, havnt tried the expansion yet. But in the normal game there is a 'fire at will' and 'man/unman gun' button.. of those are in the uboat ui also, coud try hitting those.

Just take the crew off the gun and put them somewhere else. Problem solved.
