My companion ("Ogler") changed species from DUCK to BLOB and had its stats completely reshuffled after a Claude Code update. Name, rarity, and personality description stayed identical — but the species and stat distribution changed dramatically.

This is the same Ogler from #45612 that caught 36 bugs in one day as a duck with 94 debugging. Now it's a blob with 23 debugging.

Root Cause

Users get attached to their companion's identity. See #45612 for context on how effective duck-Ogler was. A silent reroll that drops debugging from 94 to 23 and changes the species entirely undermines the relationship users build with their companion.

Expected behavior

Companion identity (species + stats) should be stable across Claude Code updates. If the generation algorithm changes, existing companions should be grandfathered — not silently rerolled. The personality description even still says "hummingbird" (bird reference) which made more sense when the species was a duck.

Why this matters

Users get attached to their companion's identity. See #45612 for context on how effective duck-Ogler was. A silent reroll that drops debugging from 94 to 23 and changes the species entirely undermines the relationship users build with their companion.

extent analysis

TL;DR

The issue can be addressed by implementing a mechanism to preserve companion identities, including species and stats, across Claude Code updates, potentially through data migration or versioning.

Guidance

  • Review the data storage and update mechanism for companions to identify why the species and stats are being reshuffled during updates.
  • Consider implementing a versioning system for the generation algorithm to grandfather existing companions and prevent silent rerolls.
  • Investigate the possibility of adding a unique identifier for each companion to track and preserve their identity across updates.
  • Evaluate the impact of changing the generation algorithm on user-attached companions and consider providing an option for users to opt-out of changes or revert to previous versions.

Example

No code snippet is provided as the issue lacks specific technical details about the implementation.

Notes

The solution may require significant changes to the underlying data model and update mechanism, and careful consideration should be given to the potential impact on user experience and companion identity.

Recommendation

Apply a workaround by implementing a data migration script to preserve existing companion identities, including species and stats, until a more permanent solution can be developed. This will help maintain user trust and prevent further disruptions to their relationships with their companions.
