Ok, here's the situation:
I found the key and lock (by myself, without any hints

), dug the key out, dug the place where the hole is (it even told me there's a lock and a door behind it when I did), but then I got stuck. Supposedly, I'm supposed to use the key with the lock, right?
Well, I can't! In fact, after digging at the location of the lock (confirmed by the fact I was told I found it, and the close up), I can't seem to do anything with it: can't look at the lock, can't use the key on it etc.
Since the lock is close to the fence which was blocking the view of the lock dig site, I moved a bit back where I could see the hole and tried again using the key again on the hole, but again - nothing!
Am I missing anything or is it a bug?
Please - no spoilers guys.. I'd like to finish it alone. Just let me know if it's a bug or not. Thanks!
