+title: Fix Cube Session Clear
+status: Completed
+---
+
+## Objectives
+- Fix the "Clear Session" functionality in `CubeManager` which was failing to fully reset the application state.
+
+## Diagnosis
+- The previous implementation relied on setting state via props (`setPacks([])`), but depending on the timing of React's state updates and `App.tsx`'s persistence logic, the cleared state might not have been persisted to `localStorage` before a reload.
+- The `handleReset` function did not explicitly clear the `generatedPacks` and `availableLands` keys from `localStorage`, assuming the parent component would handle it via `useEffect`.
+
+## Fix Implemented
+- Refactored `handleReset` in `CubeManager.tsx`.
+- Added explicit `localStorage.removeItem('generatedPacks')` and `localStorage.removeItem('availableLands')` calls.
+- Added explicit calls to reset all local component state (`inputText`, `processedData`, etc.) and their respective storage keys.
+- Wrapped the logic in a `try/catch` block with toast notifications for feedback.
+- This ensures a robust, hard reset of the drafting session.
+
+## Verification
+- User can now click "Clear Session", confirm the dialog, and immediately see a cleared interface and toast success message.
+- Reloading the page will confirm the session is truly empty.
