Bakura and others check you get them - I did not get mine for the first Mayan accomplishment and only got partial for the second - did not get my Mythical for either. Support ticket sent for the first one but no response in over a week. I do seem to have two legendary souls now but a few days ago I did not - one was for another event achievment - think it was the Magma Beats one I did yesterday. So do watch out for that.
