Rift Ready 0.12.21 — Reliability and efficiency fixes

Updates now opens as a popup like Preferences; other sections remain pages.

• Protects unreadable preferences and saves atomically with a recovery copy.
• Reuses match-detail pages and bounds navigation history to reduce retained UI resources.
• Refreshes stale champion summaries, review context and matchup references.
• Prevents helper restart after shutdown and removes unnecessary idle/rendering work.
• Fixes a race between update downloads and background release checks.
• Preserves page navigation and review drafts; matches and unsaved reviews still block installation.

Validation passed: 769 core checks, targeted audit/navigation regressions, settings/UI/helper suites, signature checks, and installer upgrade/rollback from 0.12.20. Repeatedly opening one match retains 1 page instead of 20; no in-game FPS improvement is claimed. Fresh live-game integration remains unverified.

Original logo, most-played champion artwork, preferences, reviews and rank history are preserved. Retired overlays and unavailable recommendations remain disabled. Riot/Overwolf integration and permissions remain unresolved.

Download RiftReference-Setup.exe or use Updates in Rift Ready. The updater verifies publisher-signed metadata and installer integrity. The installer is not Windows Authenticode-signed; the experimental Game Bar widget is not included.
