Hi, which mod is it?

Post a screenshot of the error.

Also post the stdout.txt file.

For the mods;

Half the asset ships got it...

About the stdout, which part do you need?

Ok I checked the Asset Ship mod by itself and all the ships are ok. Maybe there's a conflict with another mod?

The screenshot doesn't show an error message, it just shows a placeholder cube for a missing model. Make sure the mod is actually enabled in your savegame before loading it.

You can also use Steam's verify file integrity option to check your game files and mod files to make sure nothing is corrupt/missing.

For crashes usually the end of the stdout file is the most important. But since this is not a crash, probably need the entire file. You can upload to pastebin and just link it here.

I hope this is what you mean;

The file itself was BIG, I had to split it up to get it in Pastebin.

Ok if you look in the 2nd part of the file you uploaded, you can see a ton of messages that it removed ship models because it couldn't find the mesh files. Using the Klondike as an example, the mod is looking for the meshes in "vehicle/ship/klondike" but the game has been using "vehicle/ship/klondike_v2" since the vehicle models were updated in March 2023.

That's why your stdout is so large, it's almost entirely messages about misses meshes.

The legacy meshes are still included with the game (part of the included "Legacy Vehicle Mod") so everything should still work.

Run the Steam verify file integrity to make sure your game files are complete.

Steam Integrity has run twice, no major issues.
What weird is about the 'march 2023'-thing is that I didn't encounter the problem I'm having now until the latest update(autumn 2024).
And the one thing that makes the Klondike boats on the Yukon mod and Asset Ship mod work properly, is the last mod I wanted to use!
But I have to use it to counter the 'box', like you said, and it worked...
Thanks for the help RadiKyle, although I dislike the legacy mod...

All the legacy mod does is update old vehicles to the new better versions. You don't want that?

I hate the fact that it always nestles itself in front of the mod list,
and doesn't wait to be activated.

Well that's whole point, it should always be enabled. I don't know of any reason it should ever be turned off.

I wish they made it "hidden" so that it didn't cause confusion.

It just doesn't work like other mods...
And that keeps bothering me.
The other 'mods' the developers made(example; sandbox), don't push themselves to 1st place, nor they enable themselves!

Ok well I already explained the reason why that "mod" exists and why it should be enabled 100% of the time and never disabled. Do not turn it off.
