Tetra gone too. Don't think that a screen is needed.
I can't believe that in a max sized embark with a variation of 250 in scarcity makes 330k tetra disappear, not even a single unit left behind, but with the galena still on the map with little variation. So i guess this take out the "moving vein" theory.
Of course one could argue that the galena is the deep metal and because of that is less subjected for the vein mobility, but I don't know if the world gen works this way.
