Yet Another Zombie Survivors 1.0.1b Hotfix Guide

1.0.1b removes the old 1,000 Luck cap and fixes Prologos when Easter Egg produces Black Box. The September 23 hotfix also corrects Reserve Bench's XP carry-over and Survivor aiming. If your route depends on one of these interactions, update before retrying it.

What changes your next run?

• Prologos collection: Black Box obtained through Easter Egg now counts. Check the Mission Log after updating, then retry the objective if it remains incomplete. Follow the mission checklist.
• Luck stacking: the previous cap is gone. That does not establish a best Luck build or make damage and recovery upgrades unnecessary. Compare the current choices against the problem ending your run.
• Reserve Bench: the patch fixes XP already collected on the current level being retained when its effect advances you. Older observations of lost XP should be rechecked on the updated build.
• Aiming and attack warnings: the developer lists Survivor aiming fixes and a correction for occasionally invisible enemy attack indicators.
• Upgrade decisions: highlight or hover over a Weapons or Abilities node in the level-up screen to inspect its level before committing your next choice.

Which pages should you revisit?

Start with the Ranger squad guide for Crit/Luck planning, the mission guide for progression, and Easter Egg for the linked reward route. The patch changes a cap and specific interactions; it does not supply a new global team ranking.
