The quest for setting off the fireworks is poorly designed, because you placed exactly 4 Mortars in the PE instance with a max of 40 people. Each Mortar is available to be set off by exactly ONE person, and then there is a delay OR lag. It does not matter which.
Also, Envelopes is spelled incorrectly (not envelops).
