Proxy File Cross Connection with FS5 Footage
The Sony FS5 uses the same exact file structure and naming convention for every card, which means every camera roll has the same name files. I also use one single Proxy folder for each project (instead of creating proxies next to original.) I had a bug where I imported several cards from a single shoot and created proxies for all at once, but Premiere mis-connected some of the proxies, so that the proxy showed the correct shot, but it was a shorted version that matched the length of a shot with the same name from another roll. When I toggle proxies off, it changed the clip to the OTHER master clip. I fixed the problem by deleting the footage from the project, re-importing it, and creating the proxies in another folder.
