Added relationship to laravel model doesn't exist

I've makde some changes to a laravel model php file and the changes never get picked up.

I've tried clearing the cache, adding errors, renaming/deleting the file and the site just runs as if none of these things have happened.

It also only seems to happen to this one file in particular, the other model files are fine when I add changes

Anyone had this happen before?
