This theory may be a little off. I went into a town to today whacked 3 snakes as there were only 3 and came out -6 snakes from previous snake count.
Also I think the Snake loss Glitch and Lisa's task are not related as some are speculating. Lisa's tasks take 5 snakes from the town you chose and releases them back into that same town, so the owner of that town will have 5 less count but 5 more roaming. While it is not theft it still sucks because you are not guaranteed to get them back as snakes, you may get eggs.
The Glitch if it s a glitch and not programmed by EA is just unfortunate and any tie in to friends that may have done the Lisa task against you is mere coincidence. IMO
