The config button has suddenly become greyed out and can't be opened.
Also; changing the value in the config directly doesn’t change the capacity in-game either.

Thanks for the report.

I have updated the mod description with a clearer instruction section. Please read it again — the new notes may be useful for your case.

A few important points:

• The config value is a multiplier, not the final truck capacity value.
• Existing trucks may not refresh their capacity immediately in an already existing save.
• For existing trucks, try enabling the “Overloaded trucks” edict for a moment, then turn it off again. This can force existing trucks to refresh their capacity.

Please also try creating a new sandbox game and test the config there. I just created a new game myself, changed the config, and the setting worked correctly for me.

If it still does not work in your existing save, you can also try this:

1. Disable/remove the mod from the save.
2. Load the save without the mod.
3. Save the game again.
4. Restart the game.
5. Add the mod to that saved game again.
6. Load the save and check the truck capacity.

If the config button is still greyed out after that, please send your game version and player.log so I can investigate further.

Removing & readding allowed me to change the settings (dunno why I didn't think of doing that).
