Looks like the functionality for these two buttons have been reversed, they worked OK in the latest beta build.

You mean in the MP replay controls? Not sure what you mean by "advance battle"?

Yes.

The button on the far right used to skip the whole replay and the one to the left would advance to the next action.
These actions were reversed the first time I clicked on the buttons.

But I just tested it again and now it worked like before, so maybe there was a little glitch earlier.
