The mesh for the model brewing_stand_bottles_12.json and brewing_stand_bottles_3.json have the wrong (opposite) file names. Because of that, they display as each other.

Ex. A brewing stand with a bottle in slot 3 looks like it has a bottle in slots 1 and 2, and a brewing stand with bottles in slots 1 and 2 looks like it only has a bottle in slot 3.
