it's true, I was wrong: sort of

The devs wrote in ONE guard who waits for corvo to arrive in a certain location in the Tower, before setting off on a preset path to place the whale oil tank. However, this only occurs once, and only in this level. Its just window-dressing, I am still correct in my actual assertion that guards do not replace empty canisters, as was the original claim on a different page
