Unreal Engine 4.17 Preview

Did reimport behavior change in 4.17? I used to do Import to replace skeletal meshes instead of reimporting them when I needed special settings (instead of changing them in Persona and reimporting there), but now it seems like using Import just reimports with the same settings. It’s a bit weird because if you only reimport the mesh the animations don’t update, I guess the skeleton doesn’t update when reimporting only the mesh.
