personal story step Brute Force, bug

okay so im at the part where it says defend against the undead attackers, and i killed a few waves at which point i had to help tactician sarrena get up. Now nothing happens. Im just standing around and no waves of undead come. nothing =)
so what can i do now? will it be fixed if i restart the personal story?

Thanks
