Oil heat map incorrect
We have done some testing while walking around the planet.
We thought the heat map showed the best place to set up the oil pumps in the desert, a nice yellow white area. At max time efficiency it was taking me about 5 minutes per barrel. To see what the different yields would be in different area, I decided to drop a pump on a dark purple area, and to my surprise the pump time per barrel was like 1.5 minutes.
This is counter to the want the heat maps work with every resource. Is this a know issue? Or am I just missing something?
