Sometimes when I change my Avatar once, and then, without closing the iframe, decide on a different one, the uploader persists with the last image that was uploaded, regardless of what the image selected contains. Closing the iframe, reopening it, and reuploading does not fix the issue once it presents itself. Example: I currently use ImageA. I decide that I want to use ImageB instead. I then go to my Username and choose Avatar; an iframe opens over the current page. I upload ImageB. I decide I want to use a different picture, so without closing the iframe, I upload ImageC. The image that displays (and the one that actually sticks) is ImageB, but the filename I chose to upload (which is still in the 'Browse' box) is for ImageC. To fix this, I needed to go to a different section of the site, wait a few minutes, then reattempt the upload. Is this a known issue with XenForo? If not, can it be fixed on your end? Hopefully this is fixed soon. Just in case you need more info to reproduce the bug, I'm using Chrome v58.0.3029.110.
