What you get
- Smart engine with five modes that always tells you why it shifted
- Ground sweeps on a timer with chat countdowns - clears drops, orbs, stray arrows, empty boats and carts
- Named items, pets, frames, villagers and fresh drops are never touched
- Per chunk caps for mobs, items and hoppers, plus burst guards for drop, sand and dispenser machines
- Crammed mob farms get trimmed only when the server is actually struggling, never on a healthy one
- Redstone guard that freezes lag machines, explosion cap that tames tnt spam
- Emergency halt, area clear, memory cleanup, busiest chunk finder with click to teleport
- Clean multi-page admin menu, clickable chat buttons, live dashboard map for your hotbar
- Staff alerts when the server dips - with spark installed, one click starts a profile right from the alert
