So, after walking in one direction for 3-4 hours, I eventually began to notice "Hey, I haven't seen a rock in like an hour." shaking it off, I continue into the vast distance, settle into a nice little cave by a lake, and begin working. I then decide it's time to pave some path. Little did I know, every direction I walk, 20 minutes each way at the very least, there is not a single rock. I'm not sure if this is a bug or highly unlucky world gen. I'm not on 40 minutes of walking one direction in hopes of finding the legendary rock!
After walking for another rather lengthy period of time, it looks as though there are literally no rocks at all. Possible issue during world gen?
