Assuming the user deleted the infobox without realizing it, I did not manage to reproduce the duplication of categories inside a reference tag (line 38); if I just copy/paste them they get nowikied, so it shouldn't be a vandalism.
CCing subbu and gwicke here. T52120 and T54238 come to mind, but I'm not sure if it's really a dupe.
Thanks.
