path_spline behaves strange

sometimes my models spin to any direction before rapidly returning to the path. any ideas why?

don't know if this helps, but did you try to reduce the 'dist' parameter ? did you try add more/fewer nodes ?

Do they change their angles or do they move actually?

i added more nods. they change their pan angle (i deactivated roll and dist) and leave the path for a few seconds, walk into strange directions, spin around and then return to the path. the returning to the path is faster than the rest of the path.

yes, I tested Path_spline some time ago and I found that problem

so any solution to it?
