The solution is to make the Target Location the Current Location on Finished. However, with this setup, since the CurrentLocation variable is not set until AFTER the timeline is finished, if you spam the button, the pawn will jump back to its previous location when the Timeline is called. Because of this, you have to run an IsPlaying check on the Timeline when CycleForward is called and do nothing if True. The previous method shown, although it will not force the full duration of the Timeline to play, will allow you to spam the button.
