Invite Chain Break

Controls how deep the invite chain can go. When enabled, players who were invited by another player (not directly by an admin or console) can be restricted from inviting others.

How it works: every invite record stores a depth value.

Console or admins (op / invite.admin) invite someone → that player gets depth 0
A depth-0 player invites someone → that player gets depth 1
A depth-1 player invites someone → depth 2, and so on

The max-depth value sets the highest depth that can still send invites. Players at or above that depth are blocked.

Example with max-depth: 1:

Who invites	Invited player depth	Can they invite?
Admin / Console	0	✅ Yes
Depth-0 player	1	❌ No (`1 >= max-depth`)

enabled

Key: chain-break.enabled | Type: boolean | Default: false

Enable invite chain restriction. When false, all players can freely invite up to their max-invites limit as normal.

chain-break:
  enabled: false

max-depth

Key: chain-break.max-depth | Type: integer | Default: 1

Maximum invite depth that can still invite others. Players whose depth equals or exceeds this value are blocked.

Value	Effect
`0`	Only admins/console can invite (no player can invite)
`1`	Only players directly invited by admin/console can invite
`2`	Two generations can invite; the third cannot

chain-break:
  max-depth: 1

Run /im reload
Check for YAML syntax errors
Verify file permissions

“LuckPerms limits not working”

Ensure LuckPerms installed
Set luckperms.enabled: true
Run /im reload
Check group exists: /lp listgroups
