Hi!
This update fixes the missing ores problem. Iron can be found everywhere. Other metals can only be found at lower altitudes. Ore distribution is more dense below mountains.
I also spent some time optimizing world loading/generation.
Full list of fixes:
[x] Iso transitions doesn't work? (temp fix for now)
[x] Random ores are missing in the blockscape world
[x] Optimized world loading/generation. Almost 2 times as fast on some machines!
[x] Soil layer is too thick!
Have fun!
