Hi!

Not sure if related, but I'm getting this error since todays update (I updated to 1.13.1).
This is the only plugin that I have that affects vehicles; so I unloaded it for now.

In case it is relevant; this is my config:

{
  "Allow NPCs to bypass locks": false,
  "Allow deploying locks onto vehicles owned by other players": false,
  "Allow deploying locks onto unowned vehicles": true,
  "Require cupboard auth to deploy locks onto unowned vehicles": false,
  "Auto claim unowned vehicles when deploying locks": false,
  "Auto replace vehicle ownership when deploying locks": false,
  "Allow pushing vehicles while locked out": true,
  "Cooldown to auto craft locks (seconds)": 10.0,
  "Modular car settings": {
    "Allow editing while locked out": true
  },
  "Lock sharing settings": {
    "Clan": true,
    "Clan or ally": false,
    "Friends": false,
    "Team": true
  },
  "Auto unlock idle vehicles": {
    "Enabled": true,
    "Unlock after idle time (seconds)": 7200.0,
    "Check interval seconds": 300.0,
    "Exempt owned vehicles": true,
    "Exempt vehicles near cupboards": true
  }
}​

I now have reports of other players getting kicked for checking fuel tanks; so unlikely that it is this plugin and just an Oxide or Rust server issue.

Confirmed Oxide issue, disregard all above :)
