In the Ixal beast tribe quest Tanks for Nothing, where you have to go get a loop of Garlean Fiber from a box near Castrum Centri, if you attempt to open the box before the enemy guarding it is defeated, you are given the text "dummy" instead of the usual message that goes something along the lines of "the enemy is still about!". See attached photo for an example.

Clearly this one slipped through the cracks :P I'm only a little sad it didn't say "dammy" instead XD
