@naunau0102: It can't replace vanilla buildings. No building on its own can do that. Are you sure that it was the vanilla warehouses and not my warehouses (not requiring Industries)? Those you can only have one version of, but the vanilla warehouses or the vanilla hospital disappearing wouldn't be a problem related to any buildings. Only mods can mess with that.

Hello,

How exactly do these buildings work? The same as the buildings in the vanilla game?

A few months ago, I had used buildings from the Work Shop and some of my buildings from the base game were gone. I do not risk the same if I use these buildings?

I had had the bad surprise with the hospital and the warehouses. The WS warehouses had replaced my base game warehouses.

Thanks, and a great job you do for Cities Skylines and great collection, I looked at a lot of items, congratulations.
