- 根因(LP config.yml 官方注释背书):`use-server-uuid-cache: false`(LP 默认)→ "commands using a player's username will not work **unless the player has joined since LuckPerms was first installed**"——**未进过服的玩家名永远无法解析**(与有无外网无关)。
- LP 命令是**串行异步**执行:快速连发第二条会得到 `§7[§b§lL§3§lP§7]§r §7Another command is being executed, waiting for it to finish...`(带颜色代码原文,面板如实显示);`lp export` 回包时有时无(响应与执行解耦)。felis 层无责。
