The “Walk Now, Hunt Later” feature always resets when the field monsters respawn, which usually occurs at the top of the hour. I guess they used the same logic for HAT/EDIs too.
By walking near huntathons or interceptions we are supposed to be able to do them once we find a comfortable spot, sadly there is a slight issue, if you walk by a huntathon and before you are able to do it the hour resets let’s say you picked up the huntathon at 12:50am and want to do it at 1pm then it is not possible, the game resets the monsters and sadly it removes the fact that you were near the huntathon even though the huntathon is still on going, hopefully they can find a work around where hourly resets don’t effect the huntathon itself so we can do it untill it’s timer is done.
現状/Current Status
Currently if there is an hourly reset the huntathons a player walks by get reset and won’t be able to be done unless the player walks back to the huntathon even if the timer of the huntathon is still going.
