Landfill from before the mod was added looks like vanilla landfill except at the edges with other tile types where it looks like it is supposed to, and is completely unbreakable, until updated by placing something on it, where it becomes breakable.
Placing another tile type on it (such as concrete) also says it duplicates the platforms, even though it doesn't.
Newly placed landfill also is textured wrong.
I'm using Space Exploration and Krastorio 2, if that matters.
