UBOAT234,
Ref has quite correcty noted that the reason is that you have only moved (removed) the 3D object, and not the damage zone.
I can fix this. However, time is an issue for me. Also, AG124's ships have priority as he was the only one to initially submit ships to the Dev's.
I am currently working on the NYGM Ship Damage Mod Ver 2. At the moment I have for the most part completed the small & coastal merchants, the tug boat, along with the fishing boat, small coastal vessel & the Trawler.
As has been the NYGM custom, I will be releasing these in a preview mod.
Before anyone asks, I cannot make the NYGM Ship Damage Mod Tool available for distribution because of legal issues
