-        Generate AppID using STL's exact algorithm (MD5-based).
+        Generate random AppID to avoid Steam cache conflicts.
         
-        This matches STL's generateShortcutVDFAppId and generateSteamShortID functions:
-        1. Combine AppName + ExePath  
-        2. Generate MD5 hash, take first 8 characters
-        3. Convert to decimal, make negative, ensure < 1 billion
-        4. Convert signed to unsigned for CompatToolMapping
+        Uses random negative AppID similar to old working method to avoid
+        Steam's cache conflicts that break Proton setting and "Installed Locally" visibility.
+        AppID will be re-detected after Steam restart using existing detection logic.
