Not able to destroy ships or confirm kills.
 

Title says my problem. Whenever I strike a ship with a torpedo or hit it with the deck gun enough to destroy it, it appears to take damage but never sink. In addition, the marker representing the ship on the map just disappears rather than changing to a destroyed icon. Also, I never receive a notification from my officers that he ship has been destroyed either. Do you guys have any idea what may be the cause of this?

My mod list includes:

MightyFine Crew Mod
Reworked Morale & Abilities
Dynamic Environment
Equipment and Upgrades by TheBeast
Multiple UIs for SH5 with TDC and Automation
Depth charge water disturbances
Open Horizons II

Not sure , but you definately need the AI mod IRAI .

dont use water disturbances with irai installed .

Do you have records of destroyed ships in your Captain's log?

It does record them in the captains log. However, it does not anywhere else.

If it shows in the captain's log you are ok and you got credit for it. My UIs mod does not like some of the new ships that were made. There is something wrong with them that prevents the mod from registering them as kills.

Good to know, although I think I'll just disable the water disturbances, as I am at the point where TDC makes my mind boggle and the sight of an enemy destroyer moving my direction gives me a panic attack. :dead:

nope , the game is broken without irai . just line yourself up 90deg to the target and sit the scope on 0 deg . fire a torp when you think the time it will take the torp to reach the target = the time it will take the ship to reach the 0 deg mark on your scope . this way you will get to learn distances by sight and then progress to proper tdc solutions later as you progress thru the campaign .

Okay, after doing some more tests I found out you could enable TDW own destroyed icons as well, and they work for the most part. But more importantly, the ships can be destroyed, its just that they always move forward about a minute or two, as there engines still appear to function, then stop and slowly, slowly start sinking into the water.
