just curious........sometimes when making a new post all of my smiles are either replaced with words or replaced with other peoples avatars. for example; right now i have a lima bean and a canadian flag in the smiles section while writing this. sometimes when i go back and look at old posts, they have different smiles in place of what i had originally put? thought i read a post about this happening to someone else before, but i couldn't find it. just curious as to what causes this.
