I'm having trouble with the plugin not blocking players from building in a zone with nobuild set to true. I have confirmed that no one has the permission zonemanager.ignoreflag.nobuild. I'm running the current version of zone manager. any ideas or is anyone else seeing something similar? 

here is a snippet of my zone. 

{
"Id": "raid1",
"Name": "raid1",
"Radius": 175.0,
"Location": "934.3699 2.014282 1279.512",
"Size": "0 0 0",
"Rotation": "0 0 0",
"EjectSpawns": "false",
"Flags": "NoBuild"
},

got the same issue

  {
"Id": "01",
"Name": "RB-1",
"Radius": 150,
"Location": "-1833.411 4.242188 -277.0864",
"Size": "0 0 0",
"Rotation": "0 0 0",
"EnterMessage": "You have Entered A Raidable Base Zone",
"LeaveMessage": "You have Left A Raidable Base Zone",
"Flags": "NoTp, NoBuild, NoSprays, NoEntityPickup, NoGather, NoStash"
},

I've still got the same problem. I'm running carbon, not sure if that contributes.
