Hi Everyone! And sorry for offtopic, I guess... But...
The issue is pretty old. Just can't man bow/stern gun after boat upgrade. Generally there's NO CREW SLOTS in crew management screen. But the Last one features having'em all right
Some times Dual 5.25" Gun with 20mm mount results in manning all 4 gunners a machine gun...

instead of the howitzer itself. Funny looking dudes aboard crowding around and arguing who's to man the MG this time!
Or a Big Gun manned all right and the mg is working. But the one to shoot... is the Invisible Man
Is there any way to fix it..? Any help appreciated. Realy!
