Editing Home Plate, Objects Fall Through Floor.

[MadTod]

I'm making a mod that edits Home Plate because I don't like the ruined floor or the horrible upstairs, however I've run into a problem.

 

For some reason when I tested the mod in-game, anything I try to place on the ground (in Workshop mode) just goes trough it (red outline) and isn't able to be placed (green outline).

 

Now as this happens to the whole of Home Plate and not just the floors I've replaced (it happens to the concrete to even though I haven't touched that) I figured it isn't just something to do with the floors themselves but I don't know what it is.

 

P.S. The only objects that can be placed are those with the keyword anythingisground, however I'm not going to add that to every Workshop Objects just so I can place them.

 

 

Any help would be greatly appreciated, thanks.
