After using position transfer, the charactef splinepaths become invalidrs o

I used spawn in tyflow01 to form the particle movement trajectory, and then it was ok to use the splinepath to form the siblings line. When I used birthflow in tyflow02 to get tyflow01 for position transfer, the added splinepath siblings under tyflow02 were invalid

Siblings don't transfer between flows, however you can use Set Target to set targets from siblings in your first flow, and then use the Spline Paths operator to create splines to targets in your second flow. The end result should be the same. Make sure to turn on custom float caching in the first flow as well.
