Missing scene near the end?
When the group are watching the convoy of mercs/police roll up to the towers out of the window of their apartment, the window is intact.
After Dmitri's group is wiped out, we see Nya and everyone looking down out of a now smashed window and Dolores is holding her arm as if she'd been shot (she was fine when she entered the apartment).
Is this just sloppy editing? They deleted a scene of the drones attacking the tower after realizing it was dumb idea perhaps? Should have been re shot if so.
