Kreg on Crack?

Just finished giving up on my cabinet face frame. I had some leftover Tigerwood flooring I was hoping to use, real pretty stuff. Anyway it kept on cracking and its all gone now. I'm a little surprised since I was using the Kreg system and all. All settings were for 3/4 thick wood, kreg screws, etc.
Anyone else have this problem?
