Description

Players are repeatedly receiving a "save rejected — signature mismatch" error when the game attempts to sync their save to the server. The error persists across sessions.

Steps to Reproduce

Not fully characterised — occurs during normal gameplay without any obvious trigger.

Expected Behaviour

Game saves should succeed and sync to the server without error.

Actual Behaviour

The save is rejected with a signature mismatch error. The exact conditions that trigger it are unclear but it recurs consistently for affected players.

Notes

Likely a JWT/HMAC signature validation failure on the API side — either the client is sending a stale or malformed token, or the server-side secret has rotated/mismatched. Worth checking whether this correlates with long sessions, tab restores, or multiple tabs open simultaneously.
