Same here, 5 standard generated maps, no clay in anyone of them. This game is the issue, I am pro gamer. "Rain Common" using map color. Run for 1000 blocks checking mountains and dirt level. No clay at all. Oh well. I'll request a refund, if clay is broken, I don't wanna wait for what's next. about 60 hours of 1000 enemies and 0 clay.
Comment section full of developers or friends of developers.. lol
