What happens to carts inside a tribe when the tribe hits 810 days inactive and the totem is removed.

Do they instantly become abandoned or is there a delay on them.

Got a bit of an argument going on in chat as a result of Serenity Reborn hitting the 810 days.

I've been at several tribes when they hit 810 and every single time the carts have gone abandoned the second the totem was gone, today was the first where that didn't happen.
