I really, really hope that the guy your boss sent to relieve you at least tried to wave some credit to you. I'm not generally not one to hold grudges, nor one to expect public praise, but those rare instances where someone else gets credit for my work AND I get pushed under the bus...yeah, that goes in my book of grudges. I'm almost superstitious about this and always try to spread credit to anyone involved in a win, no matter how marginal their involvement. I'm too afraid of the bad karma...or ending up in any fellow spirit-dwarf's book of grudges.
