I have been trying to change my formation during Cerberus event. Instead it uses the formation i had upon the start of the event.

I use the following notation, with 3 being the top front position.
123
456
789

My initial formation was
2 valla
3 cianna
6 Adamanti
7 shayd
8 Main
with bloodstorm in reserve
I find this formation useful for runs through the Labyrinth.

I altered it to
1 calvin
2 cianna
3 valla
7 main
8 Shayd
with bloodstom in reserve

What ends up fighting is different again:
2 valla
3 cianna
6 Calvin
7 shayd
8 main
with bloodsorm in reserve

Yes, I refreshed (twice). This seems like some sort of file corruption.
