I was at Cache and a Movie (GC1B24G) this afternoon and your TB was not in the cache.
I may have sad news about the TB that is supposed to be in this cache (Dog Fighter). While looking at the contents of this cache there was no TB to be found, but a little note fell out saying "Found this today, took dinky" written by a muggle maybe 5 or 6 years old by the hand-writing.
Hopefully I am wrong about this, but such is the life of a TB I suppose.
