Paths - going backwards?

Using path_spline(me,my.x,path_dist);

If I assign a negative value to path_dist, the entity goes a bit crazy and disappears. Is there a way to have something go along the path backwards?

Get the path_length(my); and do the negative modulo yourself, should work. Annoying that you have to do that yourself (because positive modulo works automatically) but that's how it is oftentimes.

Thanks!
