QOL: Clear all aggro when FATEs end

[Tsukiyomi84]

I was FATE farming today for demiamata and its very obvious how everyone stops using abilities when the bar is almost full so they won't get locked into combat until the FATE enemies despawn. It's super annoying.

I've been left behind a bunch of times doing fate trains where people are demiatma farming. This seems like it should be a pretty easy change to make and it would be a huge quality of life improvement for fate trains.
