I think I've noticed a bug in Episode 1 Act 3, perhaps you can confirm.
I've removed the bees from the garden and from the town square. I've dropped a piece of Wensleydale down the hatch next to the record player, and I've sent the Sniffer to it. I now realise that this wasn't what I should have done (after reading the FAQ), but it's too late...
I was trying not to use the gorgonzola (in order to get the achievement). So, when I saw the policeman drop his piece outside the police station, I left it, thinking that another solution would present itself. This piece of cheese has now disappeared.
So as far as I can tell, I can't get any more cheese. I can't pick a piece up from outside Mr Paneer's shop. There's nothing in Wallace's bedroom - I don't think I've missed a piece anywhere else, perhaps someone can let me know?
A friend of mine has also independently got stuck in exactly the same place.
Really enjoying the game - great stuff. But I am now stuck and guess I'll have to start afresh - unless anyone has a suggestion?
Thanks in advance
