Act 3: Mission 1 Help

[Scythie]

Hey guys, Im on the first mission of the 3rd act, not sure of the name.

At the start you have to jump into a jump..travel a bit..jump out and clear the area around a tower.

Ive tried twice now. Seem to have killed everyone but nothing is happening. Objective marker is still the same and there is no one around. No one seems to be doing anything?

A bug perhaps? Any ideas welcome, lol.

Thanks.
