Images are getting top level urls

I’m not 100% sure if this issue is related to your plugin, but this is the closest one that deals with redirects and changing urls. Are there any issues where images file names are getting top level urls?

Example:

If I have an image uploaded with the file name ‘image1’ I can then go to https://www.mydomain.com/image1 and it gives me the attachment page. It doesn’t redirect to the attachment page, that page is displayed as an attachment page.

I also mention your plugin, because I now see that it says it’s not compatible with WP 4.1.1.
