It has mods like Smoke on the horizon , or abandon Uboat or Weather meter which I didn't find in LSH3.
Am I doing something wrong?
UPDATE
When I replaced the modded menu_1024 file with the original menu_1024 from LSH3 the game loaded.
So the mistake must be in there somewhere.
I will keep searching and let you know.
UPDATE No 2
With the standard menu_1024 from LSH3 I managed to activate
1. The abandon Uboat mod
2. The change patrol grid mod (with a slight problem : I can not see incoming messages with M button)
3. Weather indicator to cover the hull integrity : FAILED it requires lots of changes in menu_1024 file and I can not find the error YET. But I will.
Collateral failures : Dials in the right bottom corner have altered (easy to fix)
Fuel level indicator not working properly (hopefully easy to fix)
More to came as the patrol continues.
UPDATE No 3
I really don't know how this happened but the weather meter works
The colors don't fit but I think I can live with it.
UPDATE 4
The Change Grid mod works ok
Update 5
Smoke on the horizon mod works
I am still running patrol No4 so I can not make any changes to files.
