Hello,

with this configuration, if a player connects, I receive the stuff a second time: x

{
  "Commands on connection (true/false)": true,
  "Commands on connection": [
    "give wood 500000 Tanki",
    "give stones 750000 Tanki",
    "give lock.code 1000 Tanki",
    "give wall.frame.garagedoor 1000 Tanki",
    "give door.double.hinged.metal 1000 Tanki",
    "give building.planner 1 Tanki",
    "give hammer 1 Tanki",
    "give hazmatsuit_scientist_peacekeeper 1 Tanki",
    "give metal.refined 10000 Tanki",
    "give wall.window.glass.reinforced 1000 Tanki",
    "give shutter.metal.embrasure.b 1000 Tanki",
    "give cupboard.tool 100 Tanki",
    "give bed 100 Tanki",
	"give furnace.large 100 Tanki",
	"give small.oil.refinery 100 Tanki",
	"give wall.frame.shopfront.metal 1000 Tanki",
	"give metal.fragments 250000 Tanki"

  ],
  "Commands on disconnection (true/false)": false,
  "Commands on disconnection": [
    "oxide.revoke user {name} epicstuff.temp",
    "example.cmd"
  ]
}​

It's not auto kits, it's a plugin for running commands on connection. If you want kits, I'd suggest using the Kits plugin.
