SUBSIM Radio Room Forums - Error messages when loading CW dot mod save- please help me!

I’ve installed dot mod, changed Tigerfish performance on pair with the 1980s MK 48 for more fun with British submarines in the 1984 campaign. I’ve also added the Valiant and Churchill classes to that campaign as they should be. God knows why the Swiftsure is not present, but hopefully development people can fix that.

The game once I start works swimmingly and is great fun. Once I exit the game the following error occurs while I try to load up my HMS Turbulent save to continue the game:

The following error has occurred:

Index out of range exception: Array index is out of range.
PlayerFunctions.GetPlayerTorpedoIDInTubeOnLint (Int32 tube)
PlayerFunctions.InitialiseWeapons ()
LevelLoadManager.Loadlevel ()
MissionManager.LoadTraining ()
CampaignManager.OpenMissionBriefing (Int32 taskforceID)
SaveLoadManager.LoadTheCampaign ()
MissionManager.FixedUpdate ()
Then I press try to continue (might freeze or crash)
The following error has occurred:
NullReferenceException

UnityEngine.Transform.get_position ()
SubmarineMarker .LateUpdate ()

Question:
Any idea what causes this error messages(s), and how to fix it? I can only start a new campaign, and not continue my old.
