What causes flexplate damage?

Aside from a manufacturing defect, the only things that will cause a cracked flex plate are improper torque on the plate bolts at the crank and torque converter and the most common cause of transmission to engine misalignment; sometimes caused by missing alignment dowel pins that mate the transmission to the engine.
