Lately, I have been noticing a strange issue when uploading a fresh version of xenForo to a clean directory using FileZilla. To a random set of 5-15 files, it gives me a popup saying the file already exists and asks me if I want to overwrite. I don't know how can this be if there is no older version of this file in the directory. Also, the file size is slightly different. I go with the "overwrite" option and continue the uploading. When I do a "File Health Check" in xenForo after the installation, there are never any problems. Can I be confident that the files are OK if the Health Check says it is or could I have other issues down the road? Thanks!
