Strange problem with NAM roundabout fillers

[meldolion]

Hi all,
I've a strage problem with the BLS Avenue Roundabout fillers for the new NAM: maybè It's me I'm doing something wrong...
I plop rhe roundabout, then I try to put the filler at the center of it, but keeps saying that it's already occupied 
here is a screenshot


thanks for the help!

you have to bulldoze the four tiles in the center and then plop it.

Meldolion,

Bulldoze the 2x2 grass patch that is placed when you plop down the avenue roundabout. Then you can place the filler piece lots that Barby made in the middle. The 2x2 grass patch is plopped down automatically by the avenue roundabout, and this behavior is dictated by one of the NAM's RUL files.
