Encountering a stuck door in BG3's Undercity Ruins halts progress. Apply these methods systematically:
1. Target the Door Frame (Misaligned Pathing)
Players often incorrectly target the door center. Instead:

- Move the cursor directly onto the door frame or hinges.
- Right-click and select "Open".
- This bypasses common pathing errors where the character attempts impossible routes.
2. Leverage Fast Travel Reset
Game state glitches occasionally lock doors.
- Open the map and select a surface region waypoint far from the Ruins.
- Fast Travel to that location immediately.
- Return directly to the Undercity Ruins. Loading the area anew often resolves stuck objects.
3. Force Load Transition via Adjacent Zones
Triggering a new area load sequence clears temporary flags.
- Locate a nearby transition point like stairs, ladders, or connecting tunnels leading to another zone name.
- Walk through it completely until the loading screen finishes.
- Return to the stuck door immediately. The interaction flag should be reset.
