Forum:Is that a mezzer that I hear?

I have MZ and have finished it, took all of the gear and am now testing it out in the wastes. On my adventures I go through Evergreen Mills and clear the outside, when I receive a random encounter in the northeast end of the cell that it is in. The encounter contained a wastelander and a group of raiders, all of which died easily, however, in the middle of the battler I hear what sounds like a mesmetron, with its crackley like noise. I am now searching around for it and am wondering if it has been added to the list of possible encounters with MZ? Can anybody with both MZ and the G.E.C.K. check and see if it has been added?
