Try loading it last. In the Steam Workshop settings tab for the hosted server, remove it and then re-add it to the bottom.

Curious if the load order solved this. Like try it out ourselves

I have this mod loaded in last for my locally hosted multiplayer configuration. We have yet to get it to work. Any tips or ideas?

i had same issue. try putting in through the steam workshop tab instead of the mods tab within the game. Worked for me

For some reason, this mod fails to add itself properly. You need to make sure it is added in both "Steam Workshop" and "Mods" lists.
This also happens with several other mods

Hello everyone. It worked putting the mod down bellow the load order !

- I putted both on "Steam Workshop" and "Mods" lists
- Used the Mod Manager Server mods for configuring server used mods and the load order
mods.
- And i cleanned the steamapps user folder if you dont wanto delete all the folder, try to search
for the folder called "2004998206" and delete, and try host again (try this at last option but
may solve!)

try to use all those 3 recomendations and mess around with them to find an solve for your problem.

Thank you so much! Using the mod manager I was able to get this working using the Mod Manager and load order add-on.
