Tileset problem with default defaults (qt, 3.0.0-beta1+ 5972685867)
I will shortly attach a screenshot of some desert with oil, where the oil is invisible when in shadow-fog. I remember reporting this years ago (and I think I wasn't the first), then it went away and I thought it was fixed. For years. What I did different today, was that I did a completely fresh vbox (so no scar tissue anywhere, including ~/.freeciv), git pull, make, ./fcgui --gui qt. I didn't change an options (I'm even playing it in Easy for the first time) and the problem has returned.
In the screenshot to follow, the oil is the desert, two hexes above (north) of my workers. I could see the oil when the explorer was in range.
