I tried setting my cooldown to 1 minute, and also 0 minutes, but it is as if the cooldown never ends.
[My CH47] You must wait before a new CH47 (0 min)
here is my `/oxide/config/MyCH47.json`

I tried adding the line 'use cooldown: false,' bc I saw that in the minicopter json file (didn't think it would work, but wanted to test), it doesn't work with the line there or removed.

{
  "Chat Settings": {
    "ChatColor": "#bbffb1",
    "Prefix": "[My CH47] ",
    "PrefixColor": "#149800",
    "SteamIDIcon": "76561198332562475"
  },
  "Cooldown (on permission)": {
    "Use Cooldown": false,
    "Value in minutes": "0"
  },
  "Debris Settings": {
    "Remove debris": "false"
  }
}

I just figured out that the lowest possible minute is "2."
Could you put that in the plugin notes on umod Mr Author?
