This is the second edit like this, a strange(ish) looking user-name and the last part of the page deleted. First one was in the FAQ page, yesterday's (June 4th's) was on the Effects page and made by Qa7Wfu. Both times the edit was the only change made to the Wiki by that user, as far as I can tell.
