Does the Cloaker script still work anymore?

I've been having some issues with the LUA code for spawning the Cloakers, but they cause the game to crash when I attempt to spawn them in-game. Are his files missing or what? Any answer would be great, thank you.

The files are probably changed due to the update today, though I have the same problem and its not just the cloakers its will bulls also and maybe some others.
