This is the first time I&#8217;ve had this happen, but I know why now. The stock seat post didn&#8217;t fit the aftermarket seat and machining the end to extend the slim portion that the seat clamps to, crossed into the thinner wall section of the post&#8217;s design. Fortunately it didn&#8217;t break off mid-ride. Makes for an opportunity to build a suspension seat design I&#8217;ve been thinking about. That would also have the side benefit of moving the seat further back on the frame.
