I've been leveling my fishing in Stormwind for the better half of today, and randomly without warning I'll get a massive drop in reputation from Booty Bay, Gadget, and Ratchet, while my Rep with Bloodsail Buccs will increase. I've taken a couple of screenshots that I can provide as proof, I don't understand what's going on, but it's confusing as hell.
