Troubleshooting Common Issues

Display problems dominate support tickets — most resolve with hotkeys or a client restart.

Window & Display

  • Window vanished after monitor move: Shift+F12 first, then F11.
  • Different DPI monitors inflate UI — reset scale before dragging again.
  • No visuals/sound in background: verify Steam login and GPU drivers.

Stats & Skills

  • Skill stats wrong after restart: re-open skill tree and re-apply points.
  • Decoration stats missing: unequip and re-equip item.
  • Boss kill fully heals — wait for lingering projectiles.
