Hi,
we tried to make the halloween event happen less often. I starts like every 30min.

Halloween Event": {
      "Enabled": true,
      "Display Name": "Halloween",
      "Disable Vanilla Event": true,
      "Minimum Time Between (Minutes)": 61.0,
      "Maximum Time Between (Minutes)": 70.0,
      "Minimum Online Players Required (0 = Disabled)": 0,
      "Maximum Online Players Required (0 = Disabled)": 0,
      "Announce Next Run Time": false,
      "Restart Timer On Entity Kill": true,
      "Kill Existing Event On Plugin Loaded": false
    }​

Even with "disable vanilla: true" and setting the time to 61-70 it starts every 30 minutes~.
Am i doing something wrong?

Does the console output that "The Halloween vanilla event is disabled"?

Yes



:(

I've tested it, and it can disable the Halloween vanilla event. it working
