• Custom NPC skins resolved from valid Minecraft usernames, including offline players
• Signed Mojang texture caching for reconnect/restart persistence
• NPC projection repair across chunk unload/reload and reconnects
• Transaction rollback and stock-edit recovery protections
• Optional LuckPerms support
• Optional Flan claim permission support

Commands

/shopnpc add
/shopnpc config

/shopnpc list

/shopnpcadmin and admin management require operator level 2 or the LuckPerms node:

playershopadmin

Flan

When Flan is installed, normal shop creation/movement checks:

cobbledollars_playershops:spawn_player_shop_npc

The permission appears in Flan as Allow Spawning Player Shops NPC.

Skins

Open a shop's Settings menu, choose the NPC Skin option, and type a valid Minecraft username in chat.

PlayerShops resolves the username using Mojang's Minecraft profile service, obtains the signed textures property from the Mojang session server (unsigned=false), and stores the signed texture in the shop data. The selected player does not have to be online or have joined the server before.
