My dog can't detect last landmine field in Fuel veins.

[Pineapple_pizza]

I was about to remove last threat in Jeet's territory, landmine field at east of Fuel vein. But when I went near last landmine field with my dog, landmine didn't revealed, even I got closer enough. And then, something weird is happening, dog started to smell cleared minefield, marking mine icon on the map. And it is disappearing when I get back to stronghold. Does anyone know how to fix this bug?

I have that problem as well. I can only find one minefield in fuel veins and there appears to be more mines in the one field which does not appear
