On a Primalist (Beastmaster) char each time I “T”-ported to the city and came back into the map through that teleport, my Pets do not return immediately with me. It seems like they are “running” back to me, instead teleporting back with me, as they catch up with me on the map after approx. 30 seconds. Looks a bit funny I have to say.
This doesn’t happen each time, but roughly every second time I teleport.
