Yes this crack is probably continuous (even if just a hairline) right to the vent opening at the top, and only held together by the "hood shape" and the rest of it above the vent opening. I called my seller/installer and left a message about this with the receptionist (HB Plumbing in Springfield VT). They called back a while later to let me know that they didn't skip a beat but went ahead and ordered me a replacement baffle as soon as they read the description - they will bring it by to swap it out in about a week, they are a great company. I will wait to clean behind it 'til then, don't want to chance having it break in two before then - just my luck that it would not want to cooperate and fit togther again, lol.
