I started recently with modding and wanted to play with my friend a campaign. However, when we try to use my mods, the game campaigns seem to be incompatible. Any idea what the reason could be?

This is, how my mods look in the mod manager. I noticed, that my mods are red coulored, but I have no idea what this means or how to change it. Every advice is welcome :)

to join a multiplayer game you need the same mods in the same order and loaded from the same place (workshop vs data folder)

if you are a modder who plays with his own mods you will have them in the data folder to upload them and your friend will have them in the workshop folder, you need to delete your data folder copies (data has priority over workshop) so you load them from the workshop folder like your friend.

Thank you very much. Will try this method. Fingers crossed it works :)
