NPC is blocked

A running AI agent wants to move but cannot progress: it is waiting at a closed door or absent elevator, gave up waiting and is routing around it, or has stalled against obstacles or a dense crowd and is replanning.

#Common causes

• A NavLinkState is closed (or locked) on the agent's route.
• A dynamic obstacle or other agents block the corridor.

#Fixes

• Open the link (NavLinkState.open), or react to NavLinkState.waiting in the door/elevator controller.

• Move the obstacle, use ObstacleMode::Carve so paths avoid it, or widen the passage.
