No comments on this in a while. Does it still work? I'm considering using it.

Still working well for me. i  use time (on server) based permissions for the size they can build.

Would you mind sharing your config? I'm interested in what limits people are setting.

You will notice that TriangleFoundationLimit is set to 0  as it does not seem to differentiate between the two. it also "refunds" foundations that are removed BUT will keep "counting" if the buildings are within the search range (whatever you set)
