Problems with a user's behavior on a story, with the confirmation tool

By the way, I am not accusing anyone here. I just want this sorted out.

Looks like the confirmations have been removed

I don't know who did that, but I can tell you that it wasn't me.

I know you ADDED the suggestions I just want to know who confirmed them.

You and me both.

This is why when I make a story, I only allow MYSELF to confirm casting suggestions.

When I make important stories with roles that I want to add, people keep changing my roles. So they can't do that anymore.
