Couldn't progress any further in Act 2 - Creeping Shadows because the quest objective didn't exist. It didn't even register on the map. I rebooted the game, and now the objective is there. The objective was first listed as "Talk to Zima," with no quest objective icon when I couldn't progress anymore. After rebooting the game, the objective changed to "Find the entrance to the shadow worshippers lair."

This is all happening in offline mode since online mode is still broken.
