Hello i did the tutorial from Unity to Click Move with animation : https://www.youtube.com/watch?v=OYwQFpJIFGg

i did everything like he did in the video but now my problem is, that when i click to move the character when he is standing on the position he is turning around in circles, like he is trying to find the position where he wants to move like you can see here in the .gif
