A fairly well-known bug is associated with one of the establishments of the Cluckin' Bell chain, namely the invisible sign of the menu for motorists (drive-thru). The game developers apparently decided to remove it or simply forgot to add it, only the model was removed, and the collision remained in place. This mod adds a menu sign, based on the sign from other models.
