I noticed that there are No Safe Zones at monuments like Sewer Branch and Water Treatment Plant e.g.
I have the lastest plugin version. Didn't have that bug in an older version.

there are only 2 safeZones in rust and its bandit and outpost .... for that reason there will only be zones at that 2 monuments . this plugin is spesific to safezone in game . not to crate more

I can only tell you that if I fly with my minicopter over to the Water Treatment Plant or the Sewer Branch it comes the Enter No Safe Zone message in
 specific parts of these monuments. I made a screenshot for you.
The Outpost and Bandit Camp are far away from where I shot this.

One more thing I can say. I don't get teleported away if I disconnect there.
So it seems it isn't a real No Safe Zone but I get the Enter and Leave messages.

can you maybe provide me with your Zonemanager Zone_data file to see what zones were created

Sure. https://justpaste.it/2u6pf

ok does your map have 2 outpost and 2 bandit camps . if not you zones is dubbled .. maybe just unload nosafezonesleepers and zonmanager . the delete the zone_data file then load 2 plugins again

No. It's a normal map that I just took. No created map or custom map.

I got an idea what the problem is.
I didn't delete the Zonemanager data file before wipe.
Will find out if it's what caused that next wipe.
