The pathfinding settings will go through any tile the player can normally traverse, and path around ones that it cant to a certain degree. if it can’t reach the destination because the destination is impassable, it bails out and stops.
In reality this means itll auto-dodge obstacles and bushes and so on.
tbh I don’t know what happens when landmines are spotted, test it and find out 
Its not meant to be used to explore new areas, I recommend marking minefields on your map so you dont path through them, ( if it dosnt dodge them - it might automatically )
