For the last several updates, I’ve seen pets skip by behind their players, they freeze in place for a second and then zip to the next spot and freeze again. I think it started after the update where the devs said they made changes to handle pets differently.

I mostly see players near me suddenly zip across the screen to another spot.

In both of these cases it seems the game is not updating locations often enough or fast enough.

Players are also still black silhouettes for several seconds after you enter an area.
