Troubleshooting
Crate will not open: verify dkcrates.open, crate active state, crate-specific permission, at least one valid reward, correct key mode and that the player is not already opening another crate. Preview denied: verify dkcrates.preview. Physical block will not link: use an empty CHEST/ENDER_CHEST and cancel any stale link session first.
Chest opens as a shop: update QuickShop/QuickShop-Hikari and confirm load order. Animation appears but no reward: preserve the log and crate data; do not repeatedly open until checking command syntax and inventory delivery. Language unchanged: edit languages/pt-BR.yml or en.yml rather than the legacy messages.yml, then reload.
