Should be easy enough to spot the hiding place - but where is the cache? Still got to sign that log!
Note that the cache hide is being actively used for its originally intended purpose. Please make a note in your log about the current level (you'll see what I mean) so I know if I need to top it up. And if you come to this area often, feel free to help me maintain this cache!
Congratulations to Sair81 and Sarasdor for a joint FTF here.
