I’m trying to make a spline conveyor thing where i can step through the spline and actors move on it. When they reach either side it will spawn a next actor from array on the corresponding side.

It all is working kind of. But I think when actor reaches a side sometimes they for some reason get stuck in a weird loop where it destroys and spawns new actor during the timeline but without printing out the info it all looks normal.  
(It happens always when I reach the end of array and move to end of spline. But sometimes rarely it happens randomly also.)

I have tried branches but they haven’t worked for me. I’m quite lost at what to do.

what I did was rather than use \<= or \>= . I used “Nearly equal (float)” node.

And NOT clamping the lerp value when setting current distance.
