Stuck in loading screen during main scenario daily

[Emraldilian]

So after my first real run of the big main scenario quest I began running the daily for the poetics. The first run was perfectly fine, the second as well. However, from the third onward it has begun getting worse with no changes to my computer that I know of, other than windows updates.
Now, what I speak of is loading screens after cutscenes, primarily the one of the armor with the big sword, which will catch me in a loading screen after the scene for so long I won't load back in until the party has reached the first Ultima Weapon fight, though I will get every cutscene in-between.
The severity of this tends to differ elsewhere most of the time that's the only big offender, though once I couldn't participate at all after the first scene. I don't feel too bad about this since it's pretty much an assured victory anyway, but I want to fix it in case it could happen during other parts of the game.

Update: It was recommended to me to reinstall the game onto an SSD. Will update again when I see the result of this.
