Have the EXACT same issue on new version, on core of arreat. It seems to, at some ocassion just get into an endless loop of restarting, BUT it does so without moving for me. Resume game, leave, resume game, leave etc etc. Until I manually leave the game, start another quest, start core of arreat again, and reload plugin. Sometimes it works for hours, sometimes minutes, but as soon as it statrs doing it I have to manually fix it (as stated earlier how). Therefore sadly not afkable.
EDIT: WHEN in the loop its starts leaving the game imediataly after resuming it. Meaning changing the "wait time to 50 sec" might not help at all since it doesnt even wait 20 seconds before leaving and resuming... I will try to edit it anyway, and let you know tomorrow how it went!
