@marc_max Is there a reason we can't add PWPs? I put together a hacky script a while ago that you can put in the console which then allows you to add any building and it works absolutely fine.
If the problem is that the newly added PWPs don't show up in your town, there's a byte that stores how many pwps you're meant to have in town. If the save has more pwps than the amount the byte stores, the game just doesn't load the extra pwps. The offset that has the amount of pwps is MAP_BUILDINGS - 4. If you'd like the hacky script to understand how it works, feel free to PM me.
