for long runs you just have to really pay attention to stuff like numbers that dont add up because thats a sign of a mirror mine which is important to see. and you also have to just save armor kit for as long as you can because its the best way to deal with 50/50s at the end which most of the time are caused by mirror mine. (in the picture one of the mirror mines I have marked the other one I know because there isnt actually a double mine left. but that leaves 1 mirror mine that can be in 5 or 6 different pairs of mines. if you dont have armor kit for this you will suffer)
