Isolator Bracket - X1

While changing my front isolator bracket bolts I found something very disturbing. A small crack that looks like its from the manufacturing process on one of the bolt dropouts. the crack doesn't appear to go through the entire bracket. Has anyone ever noticed this before on their own bracket? It looks like a manufacturing defect. I have seen picks by doing a google search that looks like the brackets have broken off in that exact same location.

Just a mold seam, not a crack
