I am using oxide. This could be an issue with AdminMenu as well but not sure.
here's an example for my config:
{
"Enabled": true,
"Permission": "",
"Type": "None",
"ID (for None)": 22,
"Image": "https://i.imgur.com/hJusqF8.png",
"Title": "Home Casino",
"Description": "Enables you to make a casino for your base.\nPlace wheel last to insure proper link between terminals.",
"Shortname": "",
"Stages": {
"1": {
"Permission (ex: skills.vip)": "",
"Cost": 500.0,
"Value [metabolism - value, for everyone else %]": 0.0,
"Value 2": 0.0,
"Commands": [],
"Groups": [
"OwnCasinoPremiumUse"
],
"Permissions": [
"owncasinopremium.use"
],
"Required skill stages": []
}
(I see the player with the perms and group listed in the skills data config)
