Zone manager not blocking building after thursday's rust update

We use Zone Manager to prevent people from building on our raidbase islands.  The message works ,and the zone works to define where the raidbases go -- but after Thursday's update, it no longer blocks players from building on those islands.  We didn't change anything, but it no longer does that function after the update.  I think the plugin needs an update?

Type in Console, O.Version and make sure your Oxide is up to date.

Oxide.Rust Version: 2.0.6140

 

I am running this plugin, no issues.
