Yeah its in the kitchen like it was originally, just the kitchen is larger.

Strange, I've searched the entire kitchen high and low but can't find it, maybe it's a glitch or something? I'll see if it's there on my next playthrough, but for now at least I can open the Llama tunnel door with cheats.

Nevermind, I just realized the problem, apparently I had reloaded an older save where I hadn't gotten the destroy tablet objective yet and thus the key hadn't spawned; I did so just now and it's there. So glitch after all. ;)

great thanks a lot for getting back to me on that, confirming things are working correctly is just as helpful as bug reports.
