Yeah, from my experience each time you load into an instance of Tithe farm, or relog into a Tithe farm instance, the set of coordinates within that instance changes. So when you relog after dreambot closes, the coordinate saved by the script cannot be found in your instance. By going in and out of the instance, the script can re-obtain a new set of coordinates and then work again. One way this could be solved is probably to 'set' and 'reset' the starting/reference tile after a couple of loops/interval just in case it changes or the player relogs. Not sure though tbh.
