Trouble finding clay

I am having a little trouble finding clay. Wanted to see what has changed since I last played GREAT JOB lots of fun so far. Going through the tut, got to the collecting clay and so far I had found none. Looked at 20% of the google search as most are from last year, all are saying it is just under the grass almost everywhere. (Just one block down). Did 10 test holes around my area, nothing (about 3m deep)... So far 6 starts 2 of each world available, creative and survival. All default settings- Still no clay? Any help would be really cool. Thanks.

 

So far i found Clay almost everywhere where i started to dig. It is usualy just under the dirt.

 

It is pretty much everywhere under grass. I've never had to do more than decide where I wanted to make the hole and start digging.

 

Fixed!! First did a file check everything verified ok Still no clay!!!! So deleted and reinstalled CLAY!!! Woot not sure what happened but is working now + saved game worked lol thank you so much, love the game with all the new stuff added, keep up the great work PLEASE
