On Tanoa, there is a type of wire chain mesh fence. Some sections have large breaks in the fence.
The player can freely move through the broken fence pieces, but the AI cannot.
As theses fencelines can be quite long, without any gaps other than the broken piece, AI pathfinding fails to find any path through or around the fence.
AI should be able to move through the gaps as freely as the player.
The game environment should be tested to ensure it is AI friendly.
