Bug: Ores can spawn in air if they are technically not surrounded by air, if they're around transparent blocks like snow.
Solution: Fix the spawning algorithm to treat snow, flowers, mushrooms, glass, torches, etc as air for spawning ores.
Anything else you'd like to say about it: Personally, I strongly disagree with how ore spawning works now - it discourages cave exploring in favor of strip mining, which disfavors new players. I feel that the drawback of veteran players easily obtaining ore isn't as big of a priority as encouraging new players to explore, especially when they have huge stockpiles of ores anyways.
