Another aflatoxin bug: I aflatoxined my virus, since I needed mutation material. Than I sacrificed virus, and no malignant cell apeared, the creature slot remained empty. In the next turn, I filled that slot with another virus, and I choosed to mutate it. I got fallen elf with lycantrophy. When I activated lycantrophy - elf died, turned into malignant cell, BUT instead of "infest" skill, it had "scavenger" skill. It's like slot remembered 2 trigers - MC and mutation, and simply combined those 2.
