Mesh distorsion with Flow

 From:  Mauro (M-DYNAMICS)
Hi to all:i found this problem using Flow command in the last beta-release

before flowing object's mesh was clean

close-up of bottom part ( the red arrow)

i tried to use both stretch options in Flow but results are these bumps.I tried also different mesh options during export process..maybe a bug or not correct flow's use by me?
This is a solid object so,i solve this way: trunk the spoon from the handle and flow just the second to avoid distorsions in the bottom of the spoon
