I'm not really sure if this is a bug with vBShop because I don't know what the cause is. It might be the browser's fault.
The items shown in the postbit seem to be having issues with the browser cache sometimes. Some members have reported other images showing in place of the items. Hard refreshing the page corrects it, at least for a while. This was reported a few times in the past, but it was so rare that I didn't bother looking into it. However, iOS8 apparently made it worse because several members have reported the issue recently. So I just wanted to check if there was anything in vBShop that could be encouraging it to happen.
Here is someone reporting the issue; the pink squirrel character in the screenshot is someone's avatar taking the place of a few postbit items. Thread here
