When you upload an Item to the Workshop, the Share button for that asset becomes an Update button (Note: you must be Subscribed to your Item for this to occur) and any modification made to that particular asset will contribute to a potential update to the existing workshop item. I've never had this issue before until the mass transit update. And yes, I do have 'Enable the Steam Overlay' checked, both in the settings for Steam and Cities Skylines. Even shift-tab which should open the overlay isn't working.

If it is a Steam Cloud file, the asset is removed from the Cloud. None of the buttons which should lead to any page on the Steam Workshop work in-game, including mods.

If it is a local file, the asset is removed from the user's machine.If it is a workshop item, the asset is unsubscribed from the user's subscription.Previous games made by Paradox Interactive had the Workshop added at the end of the project, almost as an afterthought. Finally, the cross button allows the user to delete the asset. One of the most important decisions regarding the actual implementation we made regarding Cities: Skylines was to design our modding tools and Steam integration from start.A cloud image is shown next to the Delete button if the item is located on the user's Steam cloud.An on/off checkbox that allows the user to enable or disable the use of the specified asset.A Share/Update button that allows the user to upload this item to the Steam Workshop.I also play Cities: Skylines live three ni.

A mini thumbnail of the asset, the name given to the asset by the user and its location in parenthesis (packagename.internal_assetname). A walkthrough and tour of how to install and activate mods for your Cities Skylines game using the Steam Workshop.
