The Jester's Cap illusion (and Queen's Masquerade) pick a random illusion when you use them. Because of the way zoning/camping works, when you zone or camp any illusions on you are reloaded. Because these drinks had a random one, your illusion would actually change each time. When we first tested the Jester's Cap the fact that the illusion changed on zoning was reported as a bug, so we decided to just make the illusion not zone. Since the drinks are fairly cheap and we couldn't think of any particular reason why someone would want to run around across multiple zones in their illusion form, it seemed like the best solution. But that also explains what you're seeing when you camp.
