It appears I have found some type of scripting dependancy or this MOD must be installed before starting a Carreer.
I added the Damage Assessment MOD while in port after I exited the game.
JSGME did not report any conflicts. I am currently using the following MODS:
RemoveUbiLogoandIntro
Accurate German Flags
A Fistful of Emblems v1.5
Better Torpedo Graphics
Torpedo Splash
Free Cam Tweak 1.0
Capthelms SH5 Audio Mod
MightyFine Less Annoying Footsteps 1.0
Conning Tower Compass Fix
Captains_Picture
Enhanced Ship Recon Manual V1.01
No Moral Cooldowns
NewUI_0_3_0_ByTheDarkWraith
TheBeasts_SH5_Commands_OrdersBar
MightyFine Crew Mod 1.1.1 Stock Faces
My crew voices stopped working when executing commands. Some Commands that worked fine before resulted in CTD, other commands didnt work at all.
I exited SH5, removed this MOD and everything works fine.
I even tried loading this MOD first and started a NEW Career and same problem persisted. That indicates some type of scripting dependancy from another MOD. Most likely the NewUI by TheDarkWraith.
