+# FlexColumnAnim Cycling Fix
+
+## Problem
+The `replaceAll` method was causing cycling to break because it wasn't properly resetting the panel positioning for cycling behavior. When `replaceAll` was called, the panels would be positioned based on the previous state, which could leave some panels outside the render radius and break the cycling.
+
+## Root Cause
+1. The `_pickNearestSurvivor` method was choosing panels based on proximity to the previous index
+2. The `replaceAll` method was using this survivor selection instead of always starting from index 0
+3. This caused panels to be positioned incorrectly for cycling, especially when the current panel wasn't at index 0
+
+## Solution
+Two key changes were made:
+
+### 1. Fixed `_pickNearestSurvivor` method
+```javascript
+_pickNearestSurvivor(prevIndex) {
+    // Always prefer index 0 for proper cycling behavior
+    if (!this._panels.length) return -1;
+    if (prevIndex < 0) return 0;
+    
+    // If we have panels, prefer index 0 for cycling to work correctly
+    return 0;
+}
+```
+
+### 2. Fixed `replaceAll` method
+```javascript
+// FIXED: Always prefer index 0 for proper cycling behavior
+if (targetIndex === -1 && this._panels.length > 0) {
+    targetIndex = 0; // Always start from index 0 for proper cycling
+}
+
+// ... later in the method ...
+
+// FIXED: Always reset to index 0 for proper cycling
+targetIndex = 0;
+```
+
+## Result
+After these changes:
+- `replaceAll` always resets to index 0 (first panel)
+- All panels are positioned correctly for cycling
+- The render radius limitation no longer breaks cycling
+- Users can navigate through all panels regardless of which panel was visible before `replaceAll`
+
+## Testing
+The fix ensures that:
+1. After `replaceAll`, the first panel is always visible
+2. Arrow key navigation cycles through all panels correctly
+3. Subsequent `replaceAll` calls don't break the cycling behavior
+4. All panels remain accessible regardless of render radius settings
