Alright, I am completely tired of having to remember which tiles have oil because for some reason they never show up if they are on water or if some sort of improvement has been made on an oil land tile. There has to be some sort of fix made from a mod I just can't find it. If it helps I am playing on PC windows 7 64 bit direct-x 10 or 11, whatever the highest one is. I do not wish to use the Ctrl+r command as it may be a quick fix, but I want it fixed so I don't have to do that.
Thanks for the effort.
