Combat NPCS refusing orders

[UltimateTrouble]

My combat NPCS keep on disobeying orders and randomly stop their movement when I give an attack/defend order to them, they move to the order location and they run back to a random chunk. Sometimes they don't even fully go to the order. This might help but they have a house icon above them when they go back.

I'm facing the same problem and looking for more information
