TROUBLESHOOTING
| Problem | Solution |
|---|---|
| "Won't build roof" | Check support (6 tiles) • Has builder • Clear path |
| "Still unroofed" | Toggle roof overlay (F9) • It's just designated, not built |
| "Remove doesn't work" | It's overhead mountain • Vanilla cannot remove |
| "Collapsed!" | Remove roof FIRST • Then delete wall/column |
| "Huge room gap" | 13+ wide needs columns • Add center support |
PRO TIPS
- Keep rooms ≤12 tiles wide when possible
- Length doesn't matter, width does
- Use columns in corners to hide them
- Roof loading zones next to freezers
- Remove roof BEFORE destroying walls
- Courtyards: Remove roof area in center
