The crazy thing is that even FF 11 has one of these. I wonder why 14 doesn't. Basically your only recourse if you think your files are messed up is to delete them out of the system folder and let the launcher download the entire game again. If you had a file checker it would just find the files that were corrupted and redownload them, saving a ton of time since most of your other files are just fine.

Pls SE. It's 2019.
