Ok I need some help, so the question came up in gchat about the rarest mount. I pitched in with a story and need to check I am not going crazy...
Story goes that a back in vanilla a GM replaced a players Mechanostrider, but accidentally sent him a color that wasn't available from the vendor, and he kept it. So technically even though its not particularly awesome in appearance, it the only one ever to exist. I believe its was something like Phosphorus Mechanostrider, I am sure I read about it on wowhead but I can't find anything on guildox, wowmounts, wowhead est.
Am I going crazy or did this happen?
