I can't seem to reproduce this, but it keeps happening at random.
The safe zones won't remove on startup for players and hence causes issues on the server for both me and players because i have to remove them.
I've turned to disabling them for now....

If there was a 'refresh zones' command of sorts that would be very helpful.

There's no crash log or anything, the zones just .. don't disappear, and if the players attempt to re-log or fix the issue with /disablezones it doesn't work and somehow they managed to get it to spawn multiple zones in one area that also won't disappear.

we've tried the existing commands that make sense... but none of them fix it.

thanks for the mod :)
