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.
| Hotkey | Action |
|---|---|
| Shift + F11 | Reset display scale |
| Shift + F12 | Reset window position |
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.
