There is a video that I uploaded on a wiki previously a year ago that has since been removed at the source site. I found a similar (replacement) video later and I tried to replace it by selecting "Replace" or clicking "Upload a new version of this file" but it did not work. Instead, it replaced the thumbnail, but not the removed video with a new one. Is this a bug in the wiki engine?
