Check your limb bolts, they may have backed out on you. I have 4 friends that shoot gaurdians and commanders and they have all had the limb bolts back out as these bows were not manufactured with lock bolts or set screws to hold the limb bolts.
Hmmmmmmm I own 2 of them that have thousands of shots through them and have never seen or heard of this.
Check the brace height and AtA I dare say the string and cables have crept and probably need replacing.
