"Diablo 4: Boss Battles and Customization Woes"
A bug in the Astaroth boss fight in Act 2 of Diablo 4 has been preventing players from completing the game. To fix it, players should quit in the boss arena, reload their save file, and retry the fight. They should also be careful where they kill the boss, as it could bug the game. If the bug is not present, an NPC will run up to the player for a quick chat, and then Act 2 will be completed. Blizzard may release a proper fix for the bug in the future.
