Having trouble loading a save game to my 4net players server.

[honda civic]

So I have been playing a multiplayer farm with some mates and i wanted to transfer it to a server so they could play without me opening up the world. I already pay for a server, so i just decided to upload the save game to it. When i try to do this i get the following error logs:

dataS/scripts/gui/CareerScreen.lua(561) : attempt to index field 'map' (a nil value)
2024-05-09 14:15 Error: Running LUA method 'update'.

I've read some forums of it potentially being certain mods that are activated, but I'm confused about that. Is it mods that are activated via the server website? Or activated on the map? If the former, do i load the game with all mods deselected and then try to upload the save game file?

Would love any help!!!! TIA
