Bugged events or Personnal story bugs
I got stuck in “Air Drop-Defend the Cauldron in the Temple of Zephyrs until the Pact reinforcements arrive”. After an hour of fighting off wave after wave of enemies with no drops in hundreds (thousands?) of kills and no progress I must conclude it was bugged with an endless loop of fighting. The golem suit was fun, though it got to be tedious after an hour.
