### Fixed
- **Potion items not working on 1.21+** — `PlayerItemConsumeEvent` now applies the configured potion effect and removes the item manually; previously the event was cancelled with no effect applied, leaving the potion permanently in inventory on newer server versions
- **Armor can be bought multiple times** — purchasing a `GIVE_ARMOR` item is now blocked when the player's current armor tier is equal to or higher than the item being bought (prevents wasting currency on redundant purchases)
- **Sharpness and Haste lost on death** — upgrade effects are now re-applied on respawn after potion effects are cleared; previously only armor protection was restored
- **QuickVoid not killing armored players** — void kill damage changed from `health + 1` to `maxHealth × 1000`; armor can absorb up to 80 % of damage, so `health + 1` left heavily-armored players alive
- **Broken placed wool drops vanilla item** — breaking a placed wool block now suppresses the default drop and gives back one unit of the custom team-colored `Wool` shop item instead of a plain named block (e.g. `Red Wool`)
- **Wool block break returned 16 items** — the wool refund was accidentally using the shop stack size (16); now correctly gives back 1 wool per broken block
- **GUI category icons showed item cost and description** — category buttons in the shop GUI now show only the category name and an optional configurable description; the underlying item's price/amount lore is no longer inherited

### Added
- **`Description` field for shop GUI categories** — each category in a GUI YAML file can now define an optional `Description:` key that is shown as the lore on the category button (example values added to `exampleGui.yml` and `exampleGui2.yml`)
