Case collapse help

I am new to reloading, today got uber frustrated.
40 S&W
Rcbs press and die.

Resizing and neck widening went great, no issues. I do a light press, turn bullet and then full seat the bullet.
Previously about 1 of 20, the case wall would collapse (looks wavy), the case wall is crumpled.
Then today, every other case/bullet is collapsed, or crumpled.

My questions,
1) how do I avoid this?
2) the crumpled bullets are no good to fire? I should tear down and rebuild?
