Since this latest update, RW is selectively publishing my files even if I say all files and resources change before publishing. In one case, it actually removed the index.php and the other file I was publishing from my root directory and left my directory structure and all files exposed. When I discovered the files were missing I went to publish the files again and even though RW says it published, it never uploaded the main index.php file that was missing. I had to manually ftp it to the server.
I have been working with RW since version 3 and have never seen this behavior. FYI, exporting the files seems to work just fine.
When I click publish on a single file, the file should upload and replace the file on the server whether or not I made a change to it. I am specifically telling it to upload and it should do it.
