this is very annoying as a necro as well. if i summon a wisp, then recall away somewhere.. i cant summon another one untill the first one times out.. sometimes it can take up to 20 minutes.. or i go back to where i was, then release it.
the auto stable and recall with you seem to only work with bonded pets. not summons or fresh tames.
if you tame say a pack horse, then recall away, it runs to your location.. or whatever direction it thinks you went until its stopped by something.. then it sits there..
you cant release it unless you find it.
it will eventually go wild.. but can take a long time.. specially if its happy.
