Okay, I am really looking forward to it!
I saw that the same problem happens right after a fight and I want to go in any direction. For one step the Pokemon stays there and than goes directly behind the player.
If you want, I can do gifs of it and post them here.
I have the same problem as shown here with the little stutter of the Pokemon, but for me it comes up if I try to leave tall grass.
Has anyone a solution for this?
This User has the same problem as me from the look of it but got no response.
