+**⚠️ LESSON LEARNED — Dark Chapter Integrated:**
+
+Initial cleanup used dangerous wildcard command:
+```bash
+# ❌ DANGEROUS - What was run initially:
+rm -f /var/lib/pterodactyl/volumes/13c80cb8-f6f8-4bfe-9cdb-823d7e951584/*.zip
+```
+
+**What went wrong:**
+- Deleted `Assets.zip` (3.3GB) - critical Hytale game assets
+- Deleted Hytale world data (stored in `/backups/`)
+- Server broke: "Failed to load any asset packs"
+- **Lost player world, had to start over**
+
+**Recovery completed:**
+- Re-downloaded Assets.zip using hytale-downloader
+- Regenerated fresh Hytale world
+- Space cleared successfully
+
+**✅ CORRECT PROCEDURE** (for future reference):
 ```bash
 ssh root@216.239.104.130
 
-# Delete Hytale backups/install files (10GB)
-rm -rf /var/lib/pterodactyl/volumes/13c80cb8-f6f8-4bfe-9cdb-823d7e951584/backups
