The enderman morph sometimes puts an enderman in your position and blocks the camera and you from interacting with anything.. it also sometimes leaves behind the enderman when you change morph.

Morphed into ghast to look at 2 endermen left behind

This is the latest version with BOP and Quark

I'm not sure whether that's vanilla problem or Metamorph's. I'll see what I can do about it, once I'll return back to working on 1.1.4. Thanks for reporting! 🙂

@Decrepitdoors by the way, could tell me how I can reproduce it. Without the description, I doubt I could fix this.
