On the campaign mission "Payback" when I take out the two shield generators the AI will freeze up and not do anything, and the Goliath tank will not spawn. This kinda sucks because I can no longer progress in the campaign whatsoever. Has anyone had this problem before and how can I fix it? I've tried disconnecting and reconnecting, logging on and off, tried at a later level, tried with other characters, tried with a party and they could see it but I could not. I have updated drivers, reinstalled the game several times. as well as scanning the game for bugs and updates, so far nothing has worked. I use a GTX 1070 TI with 16gb of ram.
