I'm using the Rust kits plugin as it says, and my config looks like this:

{
"Kit Names & Cooldowns - Cooldowns (minutes)": {
"Thug": 300.0,
"Mobster": 300.0,
"Mobboss": 300.0,
"Mafia": 300.0,
"PvP": 300.0,
"Scrap": 300.0,
"Resources": 300.0,
"Crook": 300.0
},
"Use GUI Kits (true/false)": false
}

And everytime I wipe it just doesn't work, and I don't know why.

Did you clean the kits_data.json from the data folder?

No, should I delete it? Then oxide.reload * ?

Merged post

If I cleaned that folder surely it would delete everyones permissions to kits?

That will delete everyones kits permissions right though?

/kit resetdata => reset player data on wipe for kits

Every wipe I keep de kits.json but remove kits_data.json. Also lots of other data files. Some I have to keep.

kits_data.json remember when someone got the kit.

Please use lowercase letters for the kit name for the config. It converts the kit names to lower case for comparisons but I believe it does not convert the config items to lower case to compare. So try that.
