I'm pretty sure this is a bug, but its kind of a neat bug. My store has 2 diffrent signsone is the standered one on the side of a house -the other a post on my doorstep, and the best part is they have diffrent wording Only poblem is that I can only change the text on 1 of the signs the other one refuses to update. Has anyone else seen this? Also does anyone know how I can change the wording on both of the signs without losing my two sign specialness?
