Its not a dev problem. I can assure placing buildings works just as intended.
Are you on a Clay pit? (looks just like flattened dirt, but when you dig you get clay)
Are you in a forest? (need to pave the ground before you can build)
Is the land flat? (needs to be leveled before buildings can be placed)
I'm guessing your problem is the first one, since you want to build a kiln to make clay.
