Tag: removelocalmods Check the Manage Mods menu. If there are mods with a pink/magenta background and no Steam icon, delete those mods. What it means is you have a local install of the mod which is overriding the likely more up-to-date Steam version. Deleting the local version will let you use the Steam version. To delete the mod you can either:
With the mod disabled, click the trash can icon to delete the mod in the Manage Mods menu.
OR go to Documents\My Games\Terraria\tModLoader\ModsDocuments\My Games\Terraria\tModLoader\Mods and delete the tmodtmod files there.
