entry_submission_end hook not being called

I have an extension I’ve built that has been using the entry_submission_end hook but for some reason the function is no longer being called on 2.4. I checked the database and it is enabled and set to run, however. I even set a die(‘Test’) right inside the function, but when I submit an entry it skips right past the function. However, the entry_submission_ready hook calls every time. Any thoughts?
