[Critical - Data Loss] Co-op save data reset after forced shutdown and crash

We have encountered two separate incidents of save data loss / rollback while playing Minecraft Dungeons 2 in offline co-op with multiple Microsoft accounts on the same Xbox console.

Incident 1 — Forced shutdown wipes co-op saves

• Setup: 3 Microsoft accounts, offline co-op session, Xbox Series X|S.

• Trigger: Console was force-shut-down (held power button) while the party was in an active mission.

Result after relaunch:

• All 3 accounts' saves were reset to Level 1.

• Main story mission progress reset to zero for all 3 accounts.

• Equipped gear, enchantments, and currency lost.

Incident 2 — Crash during save-to-main-menu rolls back 1 of 3 saves

- Setup: Same 3-account co-op party, offline session.

- Trigger: After completing a mission, the host selected "Save and Return to Main Menu" .

Result:

• The game crashed during the auto-save / main-menu transition.

• After relaunching, 1 of the 3 accounts' save reverted to a state approximately 2 hours earlier (level, gear, and quest progress all rolled back).

• The other 2 accounts were unaffected.
