Hey so, I noticed something while blankly staring at my tech tree, that looked a little off to me.
So here you see my expert paint and ‘snippit’ skills.
That aside, if you look at the beron image, it’s easy to see a drill mining Beron, nothing funky here.
However, when you look at the Limbalt picture, you can actually see the Beron behind it.
and when you go over to the Farsu, you see the Limbalt and Beron behind it.
and again when you look at the Ziryl, you can see the Farsu, and still see the Limbalt, and Beron behind it.
Finally, the Olzine, you can clearly see the above minerals in behind them.
Not so much as a bug per-say, but definitely something to look at.
