I'm having an issue with the expunge mission. When I make it to the boss room & I have to drop the data spikes into thr terminals--when I would go back to damage the boss it gets its shield immediately after I get there. I dont even have time to damage. I asked other players if there was a specfic thing I needed to do, but they all told me they didnt have any issues like that. I would like help. If it means anything, I did do it solo. Maybe I should try with a fireteam ?
